- Design and discovery of thioether and nicotinamide containing sorafenib analogues as multikinase inhibitors targeting B-Raf, B-RafV600E and VEGFR-2
-
New sorafenib derivatives containing thioether and nicotinamide moiety were designed and synthesized as B-Raf, B-RafV600E and VEGFR-2 multikinase inhibitors. Their in vitro enzymatic inhibitory activities against B-Raf, B-RafV600E and VEGFR-2 and their antiproliferative activities against HCT-116 and B16BL6 cell lines were evaluated and described. Most of the compounds showed potent activities against both cell lines and specific kinases. Compounds a1, b1 and c4, which exhibited the most potent inhibitory activities against B-Raf with IC50 of 21 nM, 27 nM and 17 nM, B-RafV600E with IC50 of 29 nM, 28 nM and 16 nM, VEGFR-2 with IC50 of 84 nM, 46 nM and 63 nM, respectively, and good antiproliferative activities, also demonstrated competitive antiangiogenic activities to sorafenib in in vitro HUVEC tube formation assay.

- Design, synthesis and biological evaluation of thiourea and nicotinamide-containing sorafenib analogs as antitumor agents
-
A series of thiourea and nicotinamide-containing sorafenib analogs (7a-n) were designed and synthesized and their antiproliferative activities were tested against HCT116, MDA-MB-231, PC-3 and HepG2 cell lines. Most of the compounds showed potent activities against the four cell lines, compound 7h showed better activities than sorafenib against all four cell lines, and compounds 7a and 7e showed better activities against HCT116 and MDA-MB-231 cell lines. The anti-angiogenic activities of 7e and 7h were also better than that of sorafenib in both in vitro HUVEC tube formation assay and ex vivo rat thoracic aorta ring assay.

- Efficient synthesis of novel NK1 receptor antagonists: Selective 1,4-addition of Grignard reagents to 6-chloronicotinic acid derivatives
-
A new efficient synthesis of two novel classes of NK1 receptor antagonists, among them befetupitant and netupitant, starting from 6-chloronicotinic acid is described. The introduction of the o-tolyl substituent at C(4) of the pyridine ring was achieved by a one-pot selective 1,4-Grignard addition/oxidation sequence to 6-chloronicotinic acid or a derivative of it. The scope of this addition/oxidation sequence was examined. It was also shown that the carboxylic function can be converted to a methyl amino group by a Hofmann rearrangement followed by reduction. Furthermore, a new high-yielding synthesis of 2-(3,5-bistrifluoromethylphenyl)-2-methyl propionic acid based on the carbonylation of the tertiary alcohol obtained by Grignard addition of 3,5-bis(trifluoromethyl)bromobenzene to acetone was established.
