摘要:
Cyclohexanol esters of the formula I ##STR1## are described in which the radicals have the given meaning. The compounds are pharmacologically active and may therefore be used as pharmaceuticals, in particular for treating diabetes and other diseases which are characterized by an elevated secretion of glucose from the liver or by an elevated activity of the glucose-6-phosphatase system.
摘要:
A derivative of 2-methylenepropane-1,3-diol of the general formula I ##STR1## where O--A.sup.1 and O--A.sup.2, which can be the same or different, each represents O, O--C(O), O--C(O)NH, O--C(S)NH or O--C(O)O, R.sup.1 represents an alkyl or alkenyl group of 10-22 carbon atoms, n is an integer from 1 to 11, B.sup.+ represents a quaternary ammonium group, either N.sup.+ R.sup.4 R.sup.5 R.sup.6, or N.sup.+ (Het), where R.sup.4, R.sup.5 and R.sup.6 are similar or different alkyl groups of 1-4 carbon atoms, or two or all of R.sup.4, R.sup.5 and R.sup.6 may be incorporated into a cyclic or bicyclic structure, which may contain additional hetero atoms; X.sup.- means the anion of a pharmceutically acceptable inorganic or organic acid; and R.sup.2 and R.sup.3 are the same or different, and represent hydrogen or alkl groups of 1-4 carbon atoms.The present compounds have been shown to possess a PAF antagonistic effect and an inhibitory effect on the growth of tumor cells, and are thus valuable in the human and veterinary practice as platelet aggregation inhibitors, anti-thrombotic agents, anti-asthmatic agents, anti-allergic agents, anti-inflammatory agents, anti-hypotensive agents, anti-ulcer agents, anti-psoriatic agents, anti-graft rejection agents, anti-conception agents and anti-tumor agents.

摘要:
The invention relates to fluoroacrylic monomers of formula: ##STR1## in which R.sub.f denotes a perfluoroalkyl radical, R is hydrogen or a methyl radical, R' denotes an alkyl or cycloalkyl radical, or --NR'-- denotes a 1, 4-piperazinylene radical, W and Z denote divalent connecting groups, Q is oxygen or sulphur or an --NR"-- group, R" denoting hydrogen an alkyl radical, and A is a C.sub.2 or C.sub.3 alkylene group. The polymers (homo- or copolymers) derived from these monomers may be used for the water-repellency and oil-repellency treatment of various substrates, particularly leather.
摘要:
Substituted amino carbamate derivatives corresponding to the formula ##STR1## are effective in stabilizing organic materials against oxidative, thermal and actinic degradation, said derivatives being particularly effective as color improvers and process stabilizers in organic materials containing phenolic antioxidants and/or metal salts of fatty acids and/or hindered amine light stabilizers and/or organic phosphorus compounds; and certain of said derivatives as new compounds.
