Drug to ‘cure’ cravings-compound found in the bark of an African bush may hold clues to the development of drugs for reversing a host of addictive behaviours from drug
(–)-18-Methoxycoronaridine (18-MC)
A compound found in the bark of an African bush may hold clues to the development of drugs for reversing a host of addictive behaviours from drug and alcohol abuse and even smoking and compulsive over-eating, scientists reported at the BIO convention in Chicago, US, in April 2013.

(–)-18-Methoxycoronaridine (18-MC) is a derivative of ibogaine invented in 1996 by the research team around the pharmacologist Stanley D. Glick from the Albany Medical College and the chemist Martin E. Kuehne from the University of Vermont. In animal studies it has proved to be effective at reducing self-administration of morphine, cocaine, methamphetamine, nicotine and sucrose. 18-MC is a selective α3β4 nicotinic antagonist and, in contrast to ibogaine, has no affinity at the α4β2 subtype nor at NMDA-channels nor at the serotonin transporter, and has significantly reduced affinity for sodium channels and for the σ receptor, but retains modest affinity for the μ and κ opioid receptors. The sites of action in the brain include the medial habenula, interpeduncular nucleus, dorsolateral tegmentum and basolateral amygdala. It has also been shown to produce anorectic effects in obese rats, most likely due to the same actions on the reward system which underlie its anti-addictive effects against drug addiction.
18-MC has not yet been tested in humans. In 2002 the research team started trying to raise funds for human trials, but were unable to secure the estimated $5 million needed. Efforts to raise funds for future trials are still ongoing. In January 2010, Obiter Research, a chemical manufacturer in Champaign, Illinois, signed a patent license with Albany Medical College and the University of Vermont allowing them the right to synthesize and market 18-MC and other congeners.
A number of derivatives of 18-MC have also been developed, with several of them being superior to 18-MC itself, the methoxyethyl congener ME-18-MC being more potent than 18-MC but with similar efficacy, and the methylamino analogue 18-MAC being more effective than 18-MC but with around the same potency. These compounds were also found to act as selective α3β4 nicotinic acetylcholine antagonists, with little or no effect on NMDA receptors.

Impotence: When You Can’t Get It Up is Getting You Down
Probably nothing devastates a man more than having a failure in the bedroom. Impotence or erectile dysfunction affects nearly 33 million men in the United States. You are not alone. Help is available for nearly every man who has erectile dysfunction.
Diet
According to the Urology Channel’s “Erectile Dysfunction: Natural/Alternative Treatments,” erectile dysfunction can be treated by eating right, drinking plenty of water and avoiding sugar, dairy and caffeine. They recommend to eat whole, fresh, unrefined and unprocessed foods, including vegetables, whole grains, soy, beans, seeds, nuts, olive oil and cold-water fish such as salmon and tuna.
Taking your vitamins can also help; the Urology Channel suggests supplements such as flaxseed, and in particular vitamins C, E and the mineral zinc. These vitamins and supplements help bolster the vascular system, which is an important part of good sexual health.
Exercise
Since sexual health relies on the vascular system, a strong heart…

Drug development can be a gas

Pharmaceutical and biotech industries are heavily dependent on gas mixtures to grow biological cultures
The pharmaceutical and biotech industries rely heavily on industrial gases for applications such as supercritical fluid chromatgraphy and lyophilisation. Gas supply systems theefore need to offer high purity and traceability through the supply chain

Everolimus
Novartis announced it achieved its primary endpoint of significantly extending progression-free survival with Afinitor (everolimus) in Phase III trials of patients with HER2 positive advanced breast cancer.

Everolimus (RAD-001) is the 40-O-(2-hydroxyethyl) derivative of sirolimus and works similarly to sirolimus as an inhibitor of mammalian target of rapamycin (mTOR).
It is currently used as an immunosuppressant to prevent rejection of organ transplants and treatment of renal cell cancer and other tumours. Much research has also been conducted on everolimus and other mTOR inhibitors for use in a number of cancers.
It is marketed by Novartis under the tradenames Zortress (USA) and Certican (Europe and other countries) in transplantation medicine, and Afinitor in oncology.
GSK’s Votrient meets primary objective in Phase III ovarian cancer trial

pazopanib
GlaxoSmithKline’s (GSK) Votrient (pazopanib) has met the primary objective of a statistically significant improvement in the time to disease progression or death that is the progression-free survival (PFS) against placebo in Phase III ovarian cancer..
Pazopanib (trade name Votrient) is a potent and selective multi-targeted receptortyrosine kinase inhibitor of VEGFR-1, VEGFR-2, VEGFR-3, PDGFR-a/β, and c-kit that blocks tumor growth and inhibits angiogenesis. It has been approved for renal cell carcinoma and soft tissue sarcoma by the U.S. Food and Drug Administration.Pazopanib may also be active in ovarian cancer Pazopanib also appears effective in the treatment of non-small cell lung carcinoma.
New Drug Target Identified For Treating Deadly Form Of Leukemia
A research team in Singapore has identified a promising drug target for the treatment of patients with terminal-stage chronic myeloid leukemia (CML).
AsianScientist (Jun. 4, 2013) – A research team in Singapore has identified ways to inhibit the function of a key protein linked to stem cell-like behavior in terminal-stage chronic myeloid leukemia (CML). The discovery makes it possible to develop drugs that may extend the survival of patients suffering from this deadly form of leukemia.read all this at

Flamel Technologies Announces FDA Approval of Bloxiverz
06/03/2013 — Flamel Technologies today announced that the U.S. Food and Drug Administration (FDA) has approved the company’s New Drug Application (NDA) for Bloxiverz (neostigmine methylsulfate), a drug used intravenously in the operating room for the reversal of the effects of non-depolarizing neuromuscular blocking agents after surgery. Flamel expects to launch Bloxiverz in July 2013 in 0.5 and 1.0 mg/mL strengths
Chemistry
Neostigmine, N,N,N-trimethyl-meta-(dimethylcarbomoyloxy)-phenylammonium methylsulfonate, which can be viewed as a simplified analog of physostigmine, is made by reacting 3-dimethylaminophenol with N-dimethylcarbamoyl chloride, which forms the dimethylcarbamate, and its subsequent alkylation using dimethylsulfate forming the desired compound. ![]()
- J.A. Aeschlimann, U.S. Patent 1,905,990 (1933).
Neostigmine shows notable UV/VIS absorption at 261nm, 267nm, and 225nm.
Neostigmine’s 1H NMR Spectroscopy reveals shifts at: 7.8, 7.7, 7.4, 7.4, 3.8, and 3.1 parts per million. The higher shifts are due to the aromatic hydrogens. The lower shifts at 3.8ppm and 3.1ppm are due to the electronic withdrawing nature of the tertiary and quarterary nitrogen, respectively.
