摘要:
The present invention relates to methods and compositions that affect the GTP-binding activity of members of the Rho family GTPases, preferably Rac GTPases (Rac1, Rac1b, Rac2 and/or Rac3).
摘要:
The present invention provides a process of producing cisatracurium compounds, e.g., cisatracurium besylate, from isoquinolinium salts of the structural formula (VIIA) wherein X- is an anion and R is H or a C1-C6 alkyl, or an activated form of the carboxylic acid with 1,5-pentanediol to form a cisatracurium salt, optionally via an intermediate compound (VIII). The cisatracurium compounds can be purified using simple techniques to afford pure cisatracurium besylate without the need for HPLC purification.
摘要:
The invention provides compounds of general Formula (I)
wherein,
A is a cyclic group being an optionally substituted aryl group or an aromatic heterocyclic group; or A is a cyclic group R A1 R A2 C-CR A3 R A4 wherein R A2 and R A3 , together with the carbon atoms to which they are attached form an optionally substituted saturated or unsaturated carbocyclic or heterocyclic group and R A1 and R A4 are as defined below or together form a bond; or A is a non-cyclic group R A1 R A2 C-CR A3 R A4 wherein R A1 - R A4 are as defined below and R A2 and R A3 may optionally together form a bond; Z is a carbon or a heteroatom; n is selected from 0, 1, 2 or 3; and R A1-A4 , W, X and Y may be the same or different and each are selected from hydrogen, optionally substituted alkyl, optionally substituted alkenyl, optionally substituted alkynyl, optionally protected hydroxy, optionally substituted amino, optionally substituted alkoxy, optionally substituted alkenoxy, optionally substituted alkynoxy, optionally substituted aryl, optionally substituted heterocyclyl, carboxy, carboxy ester, carboxamido, acyl, acyloxy, mercapto, optionally substituted alkylthio, halogen, nitro, sulfate, phosphate and cyano, or W and X, together with the nitrogen and carbon atoms to which they are attached, form a saturated or unsaturated nitrogen containing heterocyclic group which may be optionally substituted or optionally fused to a saturated or unsaturated carbocyclic group, aryl group or heterocyclic group; or pharmaceutically acceptable derivatives and salts, racemates, isomers and/or tautomers thereof; provided that the compound is not one selected from Lamellarin A-N, S-X; D, L, K, M, N-triacetate; I-acetate; G-trimethyl ether; or T, U, V, Y-20-sulphate. Such compounds are useful as chemotherapeutic agents.
摘要:
A process is disclosed for preparing N-allyl compounds having general formula (I), in which (II) stands for a N-containing aromatic heterocycle; R?1, R3 and R4¿ represent independently from each other hydrogen or C¿1?-C4-alkyl; R?2¿ stands for hydrogen or methyl; n equals 1, 2, 3 or 4 and X- is an anion for rendering water-soluble. The process is characterized in that compounds having formula (II) are reacted in an aqueous medium with compounds having formula (III), in which A stands for a residue which can be split as an anion. These compounds are very suitable as brighteners for nickel-plating.
