Patent number: 8338460Abstract: Compounds of a formula (I) and their pharmaceutically-acceptable salts are disclosed. The compounds have glucokinase-activating effect and are therefore useful for treatment of diabetes and obesity. R1 and R2 each independently represent a lower alkyl group; X1 represent a group of a formula (II-1): wherein: R11 and R12 each independently represent a hydrogen atom or a lower alkyl group, or taken together with the nitrogen atom to which they bond, R11 and R12 may form a 4- to 7-membered nitrogen-containing aliphatic ring (one carbon atom constituting the 4- to 7-membered nitrogen-containing aliphatic ring may be replaced by an oxygen atom), or taken together with a carbon atom in (CH2)m, R11 and R12 may form a 4- to 7-membered nitrogen-containing aliphatic ring; m indicates an integer of from 1 to 3.Type: GrantFiled: October 5, 2007Date of Patent: December 25, 2012Assignee: MSD K. K.Inventors: Noriaki Hashimoto, Yufu Sagara, Masanori Asai, Teruyuki Nishimura

Patent number: 7452908Abstract: This invention relates to compounds which are represented by the general formula [I] [in which A stands for a group of the following formula [ao] or [b0] Ar1, Ar2 and Ar3 stand for optionally substituted phenyl; k stands for 0 or 1; m, n and s stand for 0, 1 or 2; R1 stands for hydrogen or optionally substituted lower alkyl; R2, R3, R4 and R5 either stand for hydrogen or optionally substituted lower alkyl, or R2 and R3, or R4 and R5 together stand for trimethylene and the like; R60 stands for hydrogen, alkyl, or the like; R61 and R71 either stand for alkyl and the like, or together stand for trimethylene and the like; X stands for carbonyl or methylene; Y stands for nitrogen or methine; and Q? stands for anion], and the like. The compounds of the invention exhibit selective antagonism to muscarinic M3 receptors, and therefore are useful as safe and effective agents showing little side effect, for treating diseases of the respiratory, urinary and digestive systems.Type: GrantFiled: May 5, 2004Date of Patent: November 18, 2008Assignee: Banyu Pharmaceutical Co., Ltd.Inventors: Yufu Sagara, Minaho Uchiyama, Akira Naya, Toshifumi Kimura, Tomoshige Numazawa, Toru Fujikawa, Norikazu Otake, Kazuhito Noguchi
