A series of 4-aryl-thieno[1,4]diazepin-2-one were synthesized and evaluated for their antiproliferative activities against the A375P melanoma and U937 hematopoietic cell lines. Several compounds showed very potent antiproliferative activities toward both cell lines and the activities were better than that of sorafenib, the reference standard. Derivatives were made as amide (8a–8i, 9a–9m) and urea (10a–10d, 11a–11d) with diverse hydrophobic moieties. One of the most potent inhibitor 10d, 1-(4-((4-ethylpiperazin-1-yl)methyl)-3-(trifluoromethyl)phenyl)-3-(4-(2-oxo-2,3-dihydro-1H-thieno [3,4-b][1,4]diazepin-4-yl)phenyl)urea was found to be very potent inhibitor of multi-protein kinases including FMS kinase (IC50 = 3.73 nM) and is a promising candidate for further development in therapeutics for cancer.
THIENODIAZEPINE DERIVATIVE OR PHARMACEUTICALLY ACCEPTABLE SALT THEREOF, AND PHARMACEUTICAL COMPOSITION CONTAINING SAME AS ACTIVE INGREDIENT
-
Paragraph 0126-0127, (2018/03/01)
The present invention relates to novel thienodiazepine derivatives or pharmaceutically acceptable salts thereof, and a pharmaceutical composition including the same. The thienodiazepine derivatives or pharmaceutically acceptable salts thereof exhibit selective inhibition activities against protein kinases such as c-Kit, FLT3, FMS, LYN, RAF1, VEGFR3, PDGFRa, PDGFRb, RET, etc., and thus can be used as a pharmaceutical composition for prevention or treatment of abnormal cell growth diseases.

Syntheses of phenylpyrazolodiazepin-7-ones as conformationally rigid analogs of aminopyrazole amide scaffold and their antiproliferative effects on cancer cells

scheme or table, p. 6760 - 6767 (2012/01/13)
Recently, we have reported the syntheses and antiproliferative activities of N-(5-amino-1-(4-methoxybenzyl)-1H-pyrazol-4-yl amide derivatives on melanoma cells. As a continuous work for antiproliferative agents in melanoma, here we report the synthesis of conformationally rigid analogs, phenyl-6,8- dihydropyrazolo[3,4-b][1,4]diazepin-7(1H)-one derivatives 7a-g, 8a-o and their antiproliferative activities against A375P melanoma cell line and U937 hematopoietic cell line. Most compounds showed competitive antiproliferative activities to sorafenib, the reference standard. Among them, N-(3-(1-benzyl-7-oxo-1,6,7,8-tetrahydropyrazolo[3,4-b][1,4]diazepin-5-yl)phenyl) -4-chloro-3-(trifluoro methyl)benzamide-amino-1-(4-methoxybenzyl)-1H-pyrazol-4- yl)-5-(3-(4-chloro-3-(trifluoromethyl) phenyl) ureido)-2-methylbenzamide (7b) exhibited potent activities (GI50 = 0.43 μM and 0.06 μM) on both cell lines. It has been further confirmed to be a potent and selective Raf kinases inhibitor and also mild inhibitor of PI3Kα.
