dual specificity protein kinase CLK (CDC2-like kinase)inhibitor, antineoplastic, CTX 712, XE88VQP94E
Rogocekib is an orally effective CLK 2 inhibitor, with an IC50 of 1.4 nM, showing anti-tumor activity.
Rogocekib is an orally bioavailable inhibitor of CLK family kinases, with potential antineoplastic activity. Upon oral administration, rogocekib binds to and inhibits the activity of CLK family kinases, thereby inhibiting the phosphorylation of serine/arginine-rich (SR) domain-containing splicing factors (SFs). This modulates RNA splicing, prevents the expression of certain tumor-associated genes, and inhibits tumor cell proliferation. In many cancer cells, core spliceosome proteins, including SF3B1, U2 small nuclear ribonucleoprotein auxiliary factor 1 (U2AF1), serine/arginine-rich splicing factor 2 (SRSF2) and U2 small nuclear ribonucleoprotein auxiliary factor subunit-related protein 2 (ZRSR2), are mutated and aberrantly activated leading to a dysregulation of mRNA splicing. CLK family kinases, an evolutionarily conserved group of kinases, phosphorylates various SR proteins including SR domain-containing SFs.

Pudafensine
Pudafensine
CAS 1320346-14-2
MFC17H19NO4 MW 301.34 g/mol
7-{[(1R,3s,5S)-8-azabicyclo[3.2.1]octan-3-yl]oxy}-3-methoxy2H-1-benzopyran-2-one
monoamine reuptake inhibitor, erectile dysfunction, neuropathic pain, NS18313, NS 18313, L9NG7US8GE, IP2015, IP 2015
Pudafensine is a monoamine reuptake inhibitor being developed as a potential treatment for erectile dysfunction (ED) and neuropathic pain. As a drug candidate, it works by preferentially inhibiting the reuptake of dopamine and serotonin. It is designed to be a first-line treatment for patients with organic ED who are not adequately served by existing therapies like PDE5 inhibitors.
How it works
- Pudafensine is a monoamine reuptake inhibitor that increases the levels of dopamine and serotonin in the brain by preventing their reabsorption into neurons.
- It has been shown in animal models and human trials to improve erectile function and reduce pain, including neuropathic pain.
Potential uses
- Erectile Dysfunction (ED): Pudafensine is being investigated for its potential to help men with organic ED who do not respond well to or cannot tolerate current treatments. Phase IIb clinical trial results are expected in late 2023.
- Neuropathic Pain: A clinical trial on pain involving pudafensine indicated it reduced allodynia and was well-tolerated with a favorable safety profile compared to pregabalin.
Development status
- Initiator Pharma is developing pudafensine as an oral tablet.
- Phase IIb studies for erectile dysfunction and Phase II studies for neuropathic pain have been completed, with positive results.
- The company is exploring its use in treating patients who are inadequately treated with existing medications.
Erectile dysfunction (ED)
Pudafensine, Initiator’s most advanced drug program has successfully demonstrated efficacy in a Clinicial Phase 2a Proof-of-Concept study and in a Phase 2b study to treat patients who suffer from organic erectile dysfunction (ED) that do not respond or cannot tolerate the currently marketed drugs in the PDE5i class (e.g. Viagra®, Cialis®, Levitra®).
Pudafensine strengthens the natural erection response by having a dual-action, both a central effect initiating erection and a peripheral effect potentiating erection through smooth muscle relaxation. Pudafensine is aimed for treatment of organic erectile dysfunction in patients who have erectile dysfunction (ED) due to abnormalities of the penile arteries and/or veins. Most common risk factors for organic ED are diabetes, overweight, lack of exercise, high cholesterol, high blood pressure, and cigarette smoking. Since Initiator Pharma was founded and pudafensine acquired, all preclinical development of the drug candidate to enable an application for clinical trials (CTA) has been carried out by the company’s auspices. Pudafensine is developed as a tablet that is taken orally on-demand. It is the company’s goal to be able to create a new “First-Line” treatment (recommended treatment) for the large group of men who have organic erectile dysfunction, who are sub-optimally treated with PDE5i products or for whom PDE5i treatment is contraindicated.
In Q4 2023 positive results from the Phase IIb clinical trial with pudafensine (IP2015) was announced. The Phase 2b trial is a randomized, double-blind, placebo-controlled, parallel-dosing group trial studying the efficacy and safety of high and low doses of pudafensine (IP2015) and placebo in otherwise healthy patients suffering from moderate to severe ED. The study comprises 130 patients divided into 3 parallel arms receiving a higher and a lower dose of pudafensine and placebo, respectively, with treatment duration of 4 weeks with frequent assessments of erectile dysfunction, safety and pharmacokinetics. The study has been conducted at the MAC clinical sites in the UK.
The study demonstrated statistically significant efficacy on the primary endpoint (related to improvements in intercourse settings) compared to placebo [p=0.034] and baseline [p=0.046]. Furthermore, the results were consistent throughout the study. Several other clinical endpoints related to improved intercourse activities (obtained from the International Index of Erectile Function Questionnaire, IIEF-15) demonstrated significant effects compared to the baseline. The frequency and type of adverse effects were mild to moderate and comparable to those observed in the placebo group. There was no reporting of critical safety observations.
Neuropathic pain
Pudafensine have shown effects in a human model of pain ie. in a clinical Phase I study in healthy subjects dosed with the drug pudafensine and challenged with a pain-inducing ingredient (capsaicin).
The Phase I study was a randomized, double blind, placebo controlled study in 24 healthy male subjects, investigating the effects on pain measures (hyperalgesia, allodynia, and subjects pain rating) of single doses of pudafensine, pregabalin as an active control, and placebo. The pain was induced by intradermal capsaicin. Pudafensine demonstrated a statistically significant effect on allodynia (p=0.049) and showed a dose-dependent effect on the measured pain parameters. Pregabalin (p=0.083) and IP2015 (p=0.051) tended to reduce hyperalgesia, although the effects on hyperalgesia were not statistically significant compared to placebo-treated subjects.

N-[2-[(2-amino-2-oxoethyl)-[3-(2-oxopyrrolidin-1-yl)propyl]amino]-2-oxoethyl]-2-[2-(2-fluorophenyl)ethylamino]-N-(2-methylpropyl)acetamide (BN201) is a small peptide molecule, a first-in-class neuroprotective compound. BN201 promotes the survival of cultured neural cells when subjected to oxidative stress or when deprived of trophic factors. BN201 promotes neuronal differentiation, the differentiation of precursor cells to mature oligodendrocytes in vitro, and the myelination of new axons. BN201 modulates several kinases participating in the insulin growth factor 1 pathway including serum-glucocorticoid kinase and midkine, inducing the phosphorylation of NDRG1 and the translocation of the transcription factor Foxo3 to the cytoplasm. In vivo, BN201 prevents axonal and neuronal loss, and it promotes remyelination in models of multiple sclerosis, chemically induced demyelination, and glaucoma. Bionure, a spin-off from Hospital Clínic de Barcelona that is based in California, is developing BN201 for multiple sclerosis, acute optic neuritis (AON) and glaucoma. BN201 was granted with orphan designation status for optic neuritis by the FDA. Optic neuritis is often an early sign of multiple sclerosis. The efficacy, safety, and capacity of the drug to cross the blood-brain barrier have been demonstrated in animal models, but the drug has not yet entered clinical testing.

Example 1: Exemplary synthesis of the compound of Formula I and crystallization thereof
Step A: Synthesis of 1-chloroethyl 2-fluorophenyl carbonate (3)
[0306]
A suitable reaction vessel was charged with water and sodium bicarbonate followed by the starting material 2-fluoro-phenol (1) . The mixture was cooled to a temperature of about 0～5℃ and 1-chloroethyl chloroformate (2) was added slowly while maintaining the temperature at 0～5℃. The temperature was raised to about 15 ± 5℃. When the reaction was judged complete by the disappearance of 2-fluoro-phenol (criteria: ≤ 2.0%, by HPLC) the reaction was worked up. n-Heptane was added and the organic phase was separated, washed with water and brine. The solution was concentrated, then toluene was added and the solution was concentrated again. The toluene addition and the concentration cycle were repeated once more.
[0307]
Step B: Synthesis of (S) – ( (R, S) -1- ( (2-fluorophenoxy) carbonyloxy) ethyl 2- (6-methoxynaphthalen-2-yl) propanoate (4)
[0308]
To a solution of naproxen in toluene in a suitable reaction vessel, 1-chloroethyl 2-fluorophenyl carbonate (3) and cuprous oxide was added. The temperature of the mixture was raised to about 115 ±5℃. When the reaction was judged complete by the disappearance of 1-chloroethyl 2-fluorophenyl carbonate (criteria: ≤ 2.5%, by HPLC) the reaction was worked up. Methyl tert-butyl ether was added at about 50 ± 5℃. The resulting mixture was filtered and the filtrate was collected at about 25 ± 5℃. Purified water was added into the filtrate and then the mixture was cooled to about 0 ± 5℃. The mixture was alkalified with ammonium hydroxide to a pH of about 9～11 and the organic phase was separated and washed with ammonium hydroxide and brine. The solution was concentrated, then acetonitrile was added and the solution was concentrated again. The acetonitrile addition and the concentration cycle were repeated some more times until the residual toluene was not more than 10% (by GC method) .

Medical uses
Plozasiran is indicated as an adjunct to diet to reduce triglycerides in adults with familial chylomicronemia syndrome.[1]
Familial chylomicronemia syndrome is a rare genetic disorder that affects the body’s ability to break down fats (triglycerides) in the bloodstream.[2] This leads to abnormally high levels of chylomicrons, which are particles that carry triglycerides.[2] Normal triglyceride levels are less than 150 mg/dL; levels above 500 mg/dL are considered severely high (severe hypertriglyceridemia).[2] People with familial chylomicronemia syndrome can have triglyceride levels in the thousands.[2] These high triglyceride levels can cause severe abdominal pain, inflammation of the pancreas (acute pancreatitis), and fatty deposits in the skin (xanthomas).[2] Some of these symptoms, specifically acute pancreatitis, can be life-threatening.[2]
Side effects
The most common side effects include hyperglycemia (high blood sugar), headache, nausea, and injection site reaction.[2]
History
The efficacy of plozasiran was demonstrated in a randomized, placebo-controlled, double-blind trial (NCT05089084) in adults with genetically confirmed or clinically diagnosed familial chylomicronemia syndrome maintained on a low-fat diet (≤20 grams fat per day).[2] Participants were randomly assigned to receive four total doses of plozasiran 25 mg or matching placebo, injected subcutaneously (under the skin) once every three months over a twelve-month treatment period.[2] The primary endpoint was percent change in fasting triglycerides from baseline to month ten.[2] The median percent change in triglycerides from baseline to month ten in the plozasiran treatment group was -59% compared to the placebo group.[2]
The US Food and Drug Administration granted the application for plozasiran breakthrough therapy, orphan drug, and fast track designations.[2]
Society and culture
Legal status
Plozasiran was approved for medical use in the United States in November 2025.[3]
Names
Plozasiran is the international nonproprietary name.[4]
Plozasiran is sold under the brand name Redemplo.[2][3]

To treat adults with relapsed or refractory acute myeloid leukemia with a susceptible nucleophosmin 1 mutation who have no satisfactory alternative treatment options
Ziftomenib, sold under the brand name Komzifti, is an anti-cancer medication used for the treatment of acute myeloid leukemia.[1] Ziftomenib is a menin inhibitor.[1] It is taken by mouth.[1]
Ziftomenib blocks the interaction between two proteins, menin (MEN1) and KMT2A (also known as mixed lineage leukemia protein, MLL).[2][3]
Ziftomenib was approved for medical use in the United States in November 2025.[4][5]
Ziftomenib, also known as KO539, is an orally bioavailable inhibitor of the menin-mixed lineage leukemia (MLL; myeloid/lymphoid leukemia; KMT2A) fusion protein, with potential antineoplastic activity. Upon oral administration, ziftomenib prevents the interaction between the two proteins menin and MLL, and thus the formation of the menin-MLL complex. This reduces the expression of downstream target genes and results in an inhibition of the proliferation of MLL-rearranged leukemic cells. The menin-MLL complex plays a key role in the survival, growth and proliferation of certain kinds of leukemia cells

Potrasertib is an investigational drug that is a selective inhibitor of WEE1 kinase, a protein crucial for the cell cycle. It is being studied for the treatment of various advanced solid tumors, including small cell lung cancer, ovarian, and colorectal cancers. By blocking the WEE1 kinase, potrasertib causes cancer cells with DNA damage to undergo premature, error-prone mitosis, which leads to cell death.
How it works
- Potrasertib is a serine/threonine kinase inhibitor.
- It works by targeting WEE1 kinase, which regulates the cell’s response to DNA damage.
- By inhibiting WEE1, it prevents cancer cells from repairing DNA damage before dividing, forcing them into a state that leads to cell death.
- This mechanism is particularly effective in tumors with a defective p53 gene, as these tumors rely more heavily on the WEE1 checkpoint for survival.
Potential uses
- Combination therapy: It is being explored in combination with chemotherapy (like gemcitabine and cisplatin) or radiotherapy to enhance their effectiveness against cancer.
- Monotherapy: It is also being studied as a standalone treatment for certain cancers, including ovarian, colorectal, and non-small cell lung cancer, especially those with high replication stress or WEE1 dependency.
Current status
- Potrasertib is still an investigational drug and is not yet approved for widespread clinical use.
- It is undergoing clinical trials to evaluate its safety and effectiveness in treating advanced cancers.
Potrasertib is an investigational new drug that is being evaluated by IMPACT Therapeutics for the treatment of advanced solid tumors. It is oral inhibitor of WEE1 kinase, a key regulator of cell cycle checkpoints.[1][2]

Plosaracetam (INNTooltip International Nonproprietary Name; developmental code names ABBV-552, SDI-118) is a synaptic vesicle glycoprotein 2A (SV2A) ligand which is under development for the treatment of Alzheimer’s disease and other cognition disorders.[1][3][4][2] In contrast to earlier SV2A ligands like levetiracetam and brivaracetam, polsaracetam does not have anticonvulsant activity and instead shows pro-cognitive effects.[2] The drug is being developed by UCB Biopharma and AbbVie.[1][3] As of October 2024, it is in phase 2 clinical trials for Alzheimer’s disease and phase 1 trials for cognition disorders.[1][3]
Plosaracetam is a small molecule drug. The usage of the INN stem ‘-racetam’ in the name indicates that Plosaracetam is a piracetam type amide type nootrope agent. Plosaracetam is under investigation in clinical trial NCT05199142 (A Study to Evaluate the Safety, Tolerability, and Pharmacodynamics of SDI-118 in Elderly Male and Female Study Participants With Cognitive Decline). Plosaracetam has a monoisotopic molecular weight of 330.05 Da.

2) To a cold solution (0°C) of 5-chloro-1 H-1 ,2,4-triazole (3.0 g, 1.5 eq., 29.1 mmol) in THF (100 ml) is added NaH 95% in mineral oil (0.9 g, 2 eq., 38.7 mmol). The reaction mixture is stirred during 30 minutes at 0°C to afford Solution B.
3) Solution A is added to solution B at 0°C and the reaction mixture is maintained under stirring overnight at room temperature. The mixture is quenched with water (100 ml) and extracted with AcOEt (2*100 mL). The combined organic extracts are washed with brine (100 ml), dried over MgS04 then concentrated under reduced pressure yielding 7 g of compound 7 as crude material. The crude residue is purified by chromatography on silicagel (eluent: CH2Cl2/MeOH/NH4OH 95/5/0.5 v/v/v) and recrystallized from iPr20/EtOH affording 1.6 g of (4R)-1-[(5-chloro-1 H-1 ,2,4-triazol-1-yl)methyl]-4-(3,4,5-trifluorophenyl)pyrrolidin-2-one 7 as a white solid.
