AMIDE COMPOUND

The present invention relate to a compound represented by the formula (I) or (II) wherein ring A is an optionally substituted ring (the ring should not be pyrrolidine, piperidine and piperazine), ring B is an optionally substituted aromatic ring, ring D is an optionally substituted ring, R1 and R2 are each independently a hydrogen atom or a substituent, R3 is a hydrogen atom or a C1-6 alkyl group, or R3 is bonded to ring A to form a non-aromatic ring, ring Aa is an optionally substituted aromatic hydrocarbon, Y is CH or N, Ra1 is an optionally substituted hydrocarbon group, and Ra2 and Ra3 are each independently a hydrogen atom or a substituent, or a salt thereof. The present invention provides a compound having a DGAT inhibitory activity, which is useful for the treatment or amelioration of diseases or pathologies caused by high expression or high activation of DGAT.

AMIDE COMPOUND

Disclosed is a compound represented by the formula (I) or (II) below, or a salt thereof. [In the formulae, ring A represents an optionally substituted ring (which is not a pyrrolidine, piperidine or piperazine); ring B represents an optionally substituted aromatic ring; ring D represents an optionally substituted ring; R1 and R2 independently represent a hydrogen atom or a substituent; R3 represents a hydrogen atom or a C1-6 alkyl group, or alternatively it combines with the ring A to form a non-aromatic ring; ring Aa represents an optionally substituted aromatic hydrocarbon; Y represents CH or N; Ra1 represents an optionally substituted hydrocarbon group; and Ra2 and Ra3 independently represent a hydrogen atom or a substituent.] The compound has a DGAT inhibitory effect and is useful for treatment or improvement of diseases or conditions caused by high expression or high activation of DGAT.

Syntheses and antiinflammatory activity of some 6-aryl-2,3,4,5-tetrahydro-3-pyridazinones

6-Aryl-2, 3, 4, 5-tetrahydro-3-pyridazinones (2c-22c) are obtained by dehydrocyclisation of various hydrazides formed by the reaction of appropriate methyl β-aroylpropionate and hydrazine hydrate in the presence of anhydrous sodium acetate. They show promising antiinflammatory activity during their evaluation by carrageenin induced paw edema test in rats.
