Моногидрат hcl нилотиниба

Химические свойства

Nilotinib hydrochloride monohydrate (NHM) lacks a chiral center, making it incapable of tautomerism. NHM is a chemical compound with the following name: 4-methyl-N-[3-(4-methyl-1H-imidazol1-yl)-5-(trifuoromethyl) phenyl]-3-[(4-pyridin-3-ylpyrimidin-2-yl) amino] benzamide hydrochloride monohydrate. It is a white powder with a slight yellowish or greenish-yellowish shade. At 25 °C, the aqueous solubility of NHM markedly decreases with pH. Moreover, it is almost insoluble in bufer solutions with pH values higher than 4.5. NHM shows slight solubility in ethanol and methanol. Nilotinib Hydrochloride Monohydrate is the monohydrate monohydrochloride form of nilotinib, an orally bioavailable aminopyrimidine-derivative Bcr-Abl tyrosine kinase inhibitor with antineoplastic activity.

Использование

Nilotinib Monohydrochloride Monohydrate might be useful in treatment of chronic myelogenous leukemia. It is a COVID19-related research product.

Определение

Nilotinib, also known as AMN107, is a tyrosine kinase inhibitor under investigation as a possible treatment for chronic myelogenous leukemia (CML). A Phase I clinical trial in 2006 showed that this drug was relatively safe and offered significant therapeutic benefits in cases of CML which were found to be resistant to treatment with imatinib (Gleevec), another tyrosine kinase inhibitor used as a first-line treatment for CML.

Механизм действия

Tasigna (nilotinib hydrochloride monohydrate) is an orally available signal transduction inhibitor of the Bcr-Abl kinase, c-kit and Platelet Derived Growth Factor (PDGF). Nilotinib binds to and stabilizes the inactive conformation of the kinase domain of Abl protein. In vitro, nilotinib inhibited Bcr-Abl mediated proliferation of murine leukemic cell lines and human cell lines derived from Ph+ CML patients. In vivo, nilotinib reduced the tumor size in a murine Bcr-Abl xenograft model.

Побочные эффекты

a headache, fatigue, gastrointestinal problems such as nausea, vomiting, diarrhea and constipation, muscle and joint pain, rash and other skin conditions, flu-like symptoms, and reduced blood cell count. Less typical side effects are those of the cardiovascular system, such as hypertension (high blood pressure), various types of arrhythmia, and prolonged QT interval. Interaction of nilotinib with OATP1B1 and OATP1B3 may alter its hepatic disposition and can lead to transporter mediated drug-drug interactions.
