, (2019/04/26)
The present invention relates to pharmaceutical agents administered to a subject either in combination or in series for the treatment of a Respiratory Syncytial Virus (RSV) infection, wherein treatment comprises administering a compound effective to inhibit the function of the RSV and an additional compound or combinations of compounds having anti-RSV activity.

As the best-characterized ubiquitin-like protein (UBL), small ubiquitin-related modifier (SUMO) was found to conjugate with a number of proteins to regulate cellular functions including transcription, signal transduction, and cell cycle. While E1, E2 and E3 ligases are responsible for the forward SUMOylation reaction, SUMO-specific proteases (SENPs) reversibly removeSUMOfrom the SUMOylated proteins. Recently, SENP1 was found to be a potential therapeutic target for the treatment of prostate cancers, but the design and synthesis of its inhibitors have not been reported. We designed and synthesized a series of benzodiazepinebased SENP1 inhibitors, and they showed inhibitory activity as good as IC50 = 9.2 μM (compound 38). The structure-activity relationship was also discussed.
(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).
