To detect and visualize lesions with abnormal vascularity, in conjunction with MRI
Gadoquatrane (marketed as AMBELVIST®) is a low-dose, macrocyclic gadolinium-based contrast agent (GBCA) developed by Bayer for use in magnetic resonance imaging (MRI). It is designed to enhance the visualization of lesions in the central nervous system (CNS) and other body regions in adult and pediatric patients.
Core Highlights:
- Lower Gadolinium Exposure: It requires a dose of 0.04 mmol/kg, which results in 60% less gadolinium exposure compared to standard macrocyclic GBCAs.
- Regulatory Approval: The FDA approved it in June 2026 for use in adults and pediatric patients, including term neonates. It was also approved in Japan in March 2026.
- Efficacy & Safety: Phase III clinical trials (the QUANTI studies) showed it effectively detects lesions with abnormal vascularity while maintaining an efficacy and safety profile comparable to other standard macrocyclic agents.
- Structure: Gadoquatrane features a tetrameric, macrocyclic structure that gives it high relaxivity and stability in the body

Flormotridaz (18F) (also referred to by its International Nonproprietary Name, flormotridazum) is an advanced radiopharmaceutical compound utilized in nuclear medicine. It is specifically engineered as a radioactive diagnostic tracer containing the fluorine-18 positron-emitting isotope.
Core Characteristics & Chemical Profile
- Substance Classification: Radioactive Diagnostic Agent / Small Molecule.
- Mechanism Basis: It shares core structural similarities and structural lineage with pyridazinone-based mitochondrial complex 1 (MC-1) inhibitors, heavily linking its functionality to target-specific tissues with high metabolic or mitochondrial activity.
Mechanism and Clinical Application
Like related fluorine-18 labeled pyridazinone analogues, this agent is designed for Positron Emission Tomography (PET) imaging workflows. [1]
- Administration: The agent is administered intravenously as a sterile unit dose before scanning.
- Cellular Targeting: It binds selectively to specific intracellular molecular targets (such as mitochondrial pathways) within highly active tissues.
- PET Imaging: As the Fluorine-18 radioisotope decays, it emits positrons. These positrons encounter electrons to produce gamma rays, which the PET scanner captures to map high-resolution, three-dimensional metabolic layouts of internal organ systems.
Contextual Comparison
In clinical nuclear medicine, molecular tracers tagged with Fluorine-18 offer significant clinical benefits over older Single-Photon Emission Computed Tomography (SPECT) agents. Their 110-minute half-life allows them to be manufactured at centralized cyclotron facilities and distributed directly to regional medical centres as ready-to-use unit doses, eliminating the need for an on-site cyclotron

Compound I, chemically named 2-tert-butyl-4-chloro-5-((3-((4-((2-(2-fluoro[ 18F ]ethoxy)ethoxy)methyl)-1H-1,2,3-triazol-1-yl)methyl)benzyl)oxy)pyridazine-3(2H)-one. Chemical structural formula:Molecular formula : C₂₃H₂₉Cl₁₈FN₅O₄
Molecular weight: 492.97The mechanism of action of compound I as a myocardial perfusion PET imaging agent: Once compound I enters cardiomyocytes, it can rapidly interact with respiratory chain complex I (MC-I) in mitochondria and remain in the myocardium for a long time. Preliminary animal studies showed that it has high cardiac uptake and low hepatic uptake 15 minutes after injection, and maintains a good heart-liver ratio 60 minutes after injection, showing good potential for myocardial perfusion imaging.In this application, Compound I liquid composition or Compound I is used as a myocardial perfusion PET imaging agent.Precursor of Compound I: Chemical name is methyl 2-(2-((1-(3-(((1-(tert-butyl)-5-chloro-6-oxo-1,6-dihydropyridazin-4-yl)oxy)methyl)benzyl)-1H-1,2,3-triazol-4-yl)methoxy)ethoxy)ethyl-4-methylbenzenesulfonate, chemical structural formula is:Molecular formula : C30H36ClN5O7S
Molecular weight: 646.16Amino polyethers (K222 ) are tribridged crown ether molecules with cavitary structures, and are typical nitrogen-containing cavitary ethers, belonging to the category of cavitary ethers. Due to their unique coordination properties, nitrogen-containing cavitary ethers can effectively and selectively complex transition metal and heavy metal cations, forming more stable complexes. Furthermore, they possess both lipophilic and hydrophilic properties, thus showing promising research potential.In existing technologies, the classic synthetic method for amino polyether (K
222 ) is the highly diluted method proposed by Lehn et al., which is a typical non-template ion synthesis method. The specific steps involve dissolving the starting materials 1,8-diamino-3,6-dioxane and 1,8-diacyl chloride-3,6-dioxane in a large amount of benzene solvent and heating the reaction for 8 hours. Then, a reduction reaction with lithium aluminum hydride is performed for 24 hours, followed by column chromatography separation and recrystallization to obtain amino polyether (K
222 ). This method requires a large amount of solvent, such as benzene, has a long synthetic route, is complex, has a low yield, and is not economically efficient. Besides the highly diluted method, another classic synthetic method for amino polyether (K222 ) is proposed by Kulstad and Malmsten, which uses Na 2CO 3
as a template to obtain a sodium iodide complex of amino polyether (K 222 ) in acetonitrile , and then decomplexes it using a resin to obtain amino polyether (K 222 ). The specific steps are as follows: 1,2-bis(2-iodoethoxy)ethane and benzylamine are refluxed in acetonitrile solution for 3 days. An intermediate is then obtained through post-processing. This intermediate is recrystallized from acetone and filtered to obtain a NaI complex. This complex is then decomplexed under acidic conditions using cation exchange resins and anion exchange resins to prepare amino polyether (K222 ) . This method uses simple equipment, requires little solvent, and has relatively mild reaction conditions. However, the applicant has found that the decomplexing method using ion exchange resins fails to proceed when the sodium ion content decreases to a certain level, resulting in a low yield.

3-(octadecanoyloxy)propyl 6-deoxy-6-sulfo-α-D-glucopyranoside
radiosensitizer (veterinary use), WV7377RGM8, SQAP
Teprosulvose (CAS 1983131-47-0) is a novel synthetic glycolipid, specifically a sulfoquinovosylacylpropanediol (SQAP). It is primarily developed for use in veterinary medicine as a radiosensitizer, intended to enhance the effectiveness of radiation therapy in treating malignant tumors.
1. Chemical Identity and Structure
- USAN/INN Name: Teprosulvose
- Systemic Name: 3-(octadecanoyloxy)propyl 6-deoxy-6-sulfo-$\alpha$-D-glucopyranoside
- Molecular Weight: 568.76 g/mol
- Structure: It consists of a glucose derivative (6-deoxy-6-sulfo-$\alpha$-D-glucopyranoside) linked via a propyl bridge to a long-chain fatty acid (stearic acid/octadecanoic acid).
Regulatory Data
Teprosulvose is currently in the investigational stage, primarily focused on veterinary oncology.
- USAN/INN Status: The name “Teprosulvose” was officially adopted by the USAN Council in 2024 (File LM-156).
- Classification: Radiosensitizer.
- Target Application: Adjuvant therapy for malignant tumors in animals (e.g., canine or feline cancers).
- Current Status: It has not yet received full FDA or EMA approval for human use. In the U.S., it is typically handled under Investigational New Animal Drug (INAD) protocols for clinical trials in veterinary patients.
Note: Because it is a specialized veterinary investigative agent, detailed safety data (LD50, pharmacokinetics) is generally found in specific FDA Freedom of Information (FOI) summaries or peer-reviewed veterinary oncology journals rather than standard human drug databases.
INN List 131 (WHO): Teprosulvose was officially included in the World Health Organization’s International Nonproprietary Names (INN) list in 2024. This confirms its unique status as a distinct drug substance.
USAN Council: The United States Adopted Names Council assigned the name in 2024, classifying it as a radiosensitizer.
FDA Status: It is currently under investigation (INAD) for canine oral melanoma and other solid tumors in veterinary medicine. Human clinical trial data is not yet widely available as the primary focus remains on the “Veterinary First” pathway.
Mechanism of Action: It is a potent inhibitor of DNA polymerase $\alpha$ and $\beta$. By inhibiting the repair of radiation-induced DNA damage, it effectively “locks in” the damage to tumor cells while sparing normal tissue due to differential uptake.

Talogreptide mesaroxetan (CAS 1801418-23-4) is a synthetic peptide, a complex molecule used as a diagnostic imaging agent with potential antitumor effects, targeting G-protein coupled receptors (GRPr) often overexpressed in cancers, allowing for specific tumor visualization in PET scans, particularly for metastatic disease detection, known for its high specificity and contrast for imaging tumors like those expressing GRPr.
Key Characteristics:
- Type: A peptide-based diagnostic agent, often labeled with radioisotopes like Copper-64 ($^{64}$Cu) for Positron Emission Tomography (PET) imaging, notes Patsnap Synapse.
- Structure: It’s a modified peptide sequence incorporating elements like PEG4 and specific amino acids, MedchemExpress.com.
- Function: Binds strongly to GRPr, helping to highlight tumors and metastatic sites.
- Application: Used in research to create high-contrast PET scans for better tumor detection and monitoring, showing promise in visualizing lymph node metastasis.
In Simple Terms:
Imagine it as a “smart tracer” that seeks out specific cancer cells. When attached to a radioactive tag, it lights up tumors on a PET scan, helping doctors see cancer more clearly, notes Patsnap Synapse.
