摘要:
The invention relates to a method for producing enantiomeric form of 2, 3-diaminopropionic acid derivatives of formula (I) by asymmetric hydrogenation from compounds of formula (II).
摘要:
Novel compounds antagonistic to both of thromboxane A2 and prostaglandin D2 receptors and medicinal compositions containing the same. As the above compounds, compounds represented by general formula (I) are found out; wherein R1 represents -CH¿2?-CH=CH-CH2-CH2-CH2-COOR?2¿ or CH=CH-CH¿2?-CH2-CH2-COOR?2¿ (wherein R2 represents hydrogen or alkyl); m is 0 or 1; p is 0 or 1; X?1 and X3¿ independently represent each optionally substituted aryl or optionally substituted heteroaryl; X2 represents a single bond, -CH¿2?-, -S-, -SO2-, -CH2-O-, -O-CH2-, -CH2-S-, -S-CH2-, etc.; and X?4¿ represents -CH¿2?-, -CH2-CH2-, -C(=O)-, etc.
摘要:
Aromatic diamide derivatives represented by general formula (I) or salts thereof and agricultural/horticultural chemicals containing the same as the active ingredient, wherein A1 represents alkylene, alkenylene or alkynylene; B represents, CO- or -C(=N-OR4)- (wherein R4 represents H, etc.); R1 to R3 represent each H, etc.; Q1 to Q5 represent each N or carbon; Y represents halogeno, etc.; m is from 0 to 5; and Z?1 and Z2¿ represent each O or S.
摘要:
The present invention provides novel compounds having a dual antagonistic activity against thromboxane A 2 receptor and prostaglandin D 2 receptor and pharmaceutical compositions comprising them. A compound of the formula (I): wherein R 1 is -CH 2 -CH=CH-CH 2 -CH 2 -CH 2 -COOR 2 or -CH=CH-CH 2 -CH 2 -CH 2 -COOR 2 ; R 2 is hydrogen or alkyl; m is 0 or 1; p is 0 or 1; X 1 and X 3 each is independently optionally substituted aryl or optionally substituted heteroaryl; X 2 is a bond, -CH 2 -, -S-, -SO 2 -, -CH 2 -O-, -O-CH 2 -, -CH 2 -S-, -S-CH 2 -, or the like; X 4 is -CH 2 -, -CH 2 -CH 2 -, -C(=O)-, or the like, have a dual antagonistic activity against both a thromboxane A 2 receptor and a prostaglandin D 2 receptor.
