Application of 1317-39-1, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Patent, and a compound is mentioned, 1317-39-1, Copper(I) oxide, introducing its new discovery.
Oxime derivatives
The invention concerns oxime derivatives of the formula I STR1 wherein R4 is hydrogen, (1-4C)alkyl, halogeno-(2-4C)alkyl, hydroxy-(2-4C)alkyl, cyano-(1-4C)alkyl, phenyl or phenyl-(1-4C)alkyl; R5 is hydrogen, (1-4C)alkyl, halogeno-(2-4C)alkyl, hydroxy-(2-4C)alkyl, cyano-(1-4C)alkyl, phenyl or phenyl-(1-4C)alkyl, or a heteroaryl moiety selected from pyridyl, pyrimidinyl, pyrazinyl, pyridazinyl, furyl, thienyl, oxazolyl and thiazolyl; A4 is (1-4C)alkylene; Ar1 is phenylene, pyridinediyl or pyrimidinediyl; A1 is a direct link to X1 or A1 is (1-4C)alkylene; X1 is oxy, thio, sulphinyl or sulphonyl; Ar2 is phenylene, pyridinediyl, pyrimidinediyl, thiophenediyl, furandiyl or thiazolediyl; R1 is hydrogen, (1-4C)alkyl, (3-C)alkenyl or (3-4C)alkynyl; and R2 and R3 together form a group of the formula –A2 –X2 –A3 — wherein each of A2 and A3 is independently (1-3C)alkylene and X2 is oxy, thio, sulphinyl, sulphonyl or imino; or a pharmaceutically-acceptable salt thereof; processes for their manufacture; pharmaceutical compositions containing them and their use as 5-lipoxygenase inhibitors.
