| Hazard Information | Back Directory | [Description]
Nintedanib esylate is a potent, oral triple angiokinase inhibitor
developed by Boehringer Ingelheim that targets proangiogenic and
pro-fibrotic pathways mediated by the vascular endothelial growth
factor receptor, fibroblast growth factor receptor and plateletderived
growth factor receptor families, as well as Src and Flt-3
kinases. It was approved for the treatment of idiopathic pulmonary
fibrosis (IPF), a condition in which the lungs become progressively
scarred over time, by the US FDA in October 2014 and by
the EMA in January 2015. The FDA granted nintedanib esylate
fast-track, priority review, orphan product, and breakthrough
designations. The drug was also approved by the EMA in November
2014 for treatment of non-small cell lung cancer in combination
with docetaxel after first-line chemotherapy. | [Chemical Properties]
Nintedanib esilate is a bright yellow powder. The octanol-water partition coefficient (log Pow) for the nintedanib esilate-free base was determined to be 3.6, demonstrating the molecule's lipophilic character. Due to the ionisable groups in nintedanib esilate, the lipophilicity profile is strongly pH-dependent. At physiological pH (pH = 7.4), the apparent partition coefficient (log D) was calculated to be 3.0. The molecule is less lipophilic in the acidic pH range (log D ≤ 1 for pH < 5). Nintedanib esilate is soluble in water. A saturated solution in water was found to have a concentration of 2.8 mg/mL and exhibited an intrinsic pH of 5.7. The solubility of nintedanib esilate is strongly pH dependent, with an increased solubility at acidic pH, particularly for pH < 3. The highest solubility of nintedanib esilate in organic solvents is observed in methanol and N-methylpyrrolidone. The best solubility in pharmaceutically relevant co-solvents is observed in propylene glycol. OFEV are soft gelatin capsules containing 100 mg or 150 mg nintedanib (as nintedanib esilate) for oral administration. Excipients: Each OFEV capsule contains medium-chain triglycerides, hard fat and lecithin.
| [Uses]
Nintedanib is a potent inhibitor of multiple receptor tyrosine kinases (RTKs) and non-receptor tyrosine kinases (nRTKs). | [Definition]
ChEBI: An organosulfonate salt obtained by combining nintedanib with one molar equivalent of ethanesulfonic acid. A kinase inhibitor used for the treatment of idiopathic pulmonary fibrosis and cancer. | [Synthesis]
The synthesis of indolinone 197 commenced with commercial
4-chloro-3-nitro-benzoic acid (194)?aesterification of which preceded
displacement of the chloride by dimethyl malonate (195)
in the presence of base to generate nitrobenzene 196. Hydrogenation
of 196 under acidic conditions furnished 6-methyoxycarbonyl-
substituted oxindole 197 by decarboxylative cyclization in
87% yield. Acylation of indolinone 197 with chloroacetic anhydride
in refluxing toluene and subsequent condensation with trimethyl
orthobenzoate resulted in indolone 198, which was isolated in
86% yield over the two-step sequence. While these two steps could
reportedly be combined into a one-pot protocol using acetic anhydride
as the solvent, the stepwise procedure was found to be more
amenable for large-scale synthesis due to fewer complications
with undesired side products. Subjection of 198 to methanolic
potassium hydroxide followed by condensation with aniline
fragment 199
in refluxing methanol and then exposure to aqueous ethanesulfonic
acid in methanol provided nintedanib esylate (XXIII) in 82%
over the three-step sequence.
Aniline fragment 199 was prepared in three steps
and 82% overall yield via initial acylation of N-methyl-4-nitroaniline
200 with chloro acetylchloride followed by displacement of
the a-amidochloride with N-methylpiperazine and hydrogenative
reduction of the nitro group gave the desired aniline.183,184

Store at -20°C | [Properties and Applications]
Nintedanib esylate (NE) is used in the treatment of idiopathic pulmonary fibrosis (IPF) and in diverse cancers, including nonsmall cell lung cancer (NSCLC). NE has a pH-dependent solubility profile with low aqueous solubility under neutral pH and increased solubility at acidic pH. The oral bioavailability of NE is 4.7% because it is a P-gp substrate and also undergoes first-pass metabolism in the liver by esterases. However, the administration of NE along with food increases the area under the curve (AUC) and maximum concentration (Cmax) when the drug is taken with food; hence, it has a positive food effect[1]. | [References]
