Page/Page column 66-67, (2008/06/13)
The invention relates to chemical compounds of the formula (I): or pharmaceutically acceptable salts thereof, which possess B Raf inhibitory activity and are accordingly useful for their anti cancer activity and thus in methods of treatment of the human or animal body. The invention also relates to processes for the manufacture of said chemical compounds, to pharmaceutical compositions containing them and to their use in the manufacture of medicaments of use in the production of an anti-cancer effect in a warm blooded animal such as man.

A benzodiazepine derivative of formula I, or a pharmaceutically acceptable salt thereof: STR1 wherein: (a) R4 is an alkyl, cycloalkyl or aryl group. (b) R10 is chosen from halo, OH, CH3, OCH3, NR11 R12, NO2, NHCHO, CO2 H and CN, and R11 and R12 are independently selected from H and alkyl (C1 -C5) or together NR11 R12 form a cyclic structure II, STR2 wherein a is 1-6; and (c) R2 is an aromatic 5- or 6-membered, substituted or unsubstituted heterocycle containing at least two heteroatoms of which at least one is nitrogen. These compounds are gastrin and/or CCK-B receptor antagonists.
(3R)-N-(1-(tert-butylcarbonylmethyl)-2,3-dihydro-2-oxo-5-(2-pyridyl)- 1H-1,4-benzodiazepin-3-yl)-N'-(3-(methylamino)phenyl)urea (YF476): A potent and orally active gastrin/CCK-B antagonist

A number of new 1,4-benzodiazepin-2-one-based gastrin/CCK-B receptor antagonists related to the archetypal analogue L-365,260, and more closely to the recently reported compound YM022, have been synthesized and evaluated for biological activity. The compounds were screened for their ability to inhibit the binding of [125I]CCK-8 to gastrin/CCK-B receptors prepared from rat brains and that of [3H]L-364,718 to CCK-A receptors from rat pancreas, and were shown to be potent and selective ligands for the gastrin/CCK-B receptor. Functional studies in vivo demonstrated the compounds to be antagonists of the receptor as evidenced by their ability to inhibit pentagastrin-induced gastric acid secretion in anesthetized rats. More extensive evaluation in viva included determination of ED50 values in the rat acid secretion model for selected compounds and an examination of the effect of these compounds on pentagastrin-induced gastric acid secretion in Heidenhain pouch dogs following oral and intravenous administration. Two compounds, i.e. (3R)-N- [1-[(tert-butylcarbonyl)methyl]-2,3-dihydro-2-oxo-5-(2-pyridyl)-1H-1,4- benzodiazepin-3-yl]-N'-[3-(methylamino)phenyl]urea, 15c (YF476), and (3R)-N- [1-[(tert-Butylcarbonyl)methyl]-2,3-dihydro-2-oxo-5-(2-pyridyl)-1H-1,4- benzodiazepin-3-yl]-N'-[3-(dimethylamino)phenyl]urea hydrochloride, 15d, showed potent dose-dependent effects in both models with the former showing excellent oral bioavailability and an ED50 of 21 nmol/kg po in dogs. 15e is currently under clinical investigation for the treatment of gastro-oesophagal reflux disease (GORD).
