- Acetamidine derivatives and their use as inhibitors for the nitric oxide synthase
-
A class of acetamidine derivatives of general formula (I) STR1 wherein R1 is hydrogen, C1-6 hydrocarbyl group optionally substituted by halo, halo, nitro, cyano or a group XR3 wherein X is oxygen, C(O)m wherein m is 1 or 2, S(O)n wherein n is 0, 1 or 2, or a group NR4 wherein R4 is hydrogen or C1-6 alkyl; and R3 is hydrogen, C1-6 alkyl, or a group NR5 R6 wherein R5 and R6 are independently hydrogen or C1-6 alkyl, provided that R3 is not NR5 R6 when X is oxygen or S(O)n; R1a and R1b are independently selected from hydrogen and halo; R2 is a C1-14 hydrocarbyl group which may optionally contain one or two heteroatoms, the group R2 being optionally substituted by one or more groups independently selected from halo; N3 ; nitro; CF3 ; ZR7 wherein Z is oxygen, C(O)m' wherein m' is 1 or 2, S(O)n' wherein n' is 0, 1 or 2, or a group NR8 wherein R8 is hydrogen or C1-6 alkyl and R7 is hydrogen, C1-6 alkyl or a group NR9 R10 wherein R9 and R10 are independently hydrogen or C1-6 alkyl; or R2 is substituted by a group (a) STR2 wherein R11 has a definition the same as for R1 ; with the proviso that when R1 is a C1-6 alkyl group and R2 is a C1-14 hydrocarbyl substituted by two groups ZR7 wherein one group ZR7 is CO2 H, the other group ZR7 is not NH2; and salts thereof, methods for the manufacture thereof, and therapies, particularly inhibtion of nitric oxide synthase, is disclosed.

- Synthesis of Unsymmetrical Functionalised Organic Sulphides
-
Acyclic thioiminium salts and the condensed thiazolium salts in the presence of aqueous sodium hydroxide as such or under base catalyzed phase transfer catalysis conditions react with appropiate organic halides to provide corresponding unsymmetrical functionalized organic sulphides.With aqueous sodium hydroxide, thioiminium salts provide the disulphides corresponding to incipient thiol.
