摘要:
This invention pertains to certain active carbamic acid compounds which inhibit HDAC activity and which have the formula (1) wherein: A is an aryl group; Q1 is an aryl leader group having a backbone of at least 2 carbon atoms; J is an amide linkage selected from: —NR1C(═O)— and —C(═O)NR1—; R1 is an amido substituent; and, Q2 is an acid leader group; and pharmaceutically acceptable salts, solvates, amides, esters, ethers, chemically protected forms, and prodrugs thereof. The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, to inhibit HDAC, and, e.g., to inhibit proliferative conditions, such as cancer and psorias

The invention provides insecticidally active compounds of formula (I): ##STR1## wherein X is nitrogen or carbon bearing a hydrogen atom; R.sup.1 is a group of formula --S(O).sub.n --Y, wherein Y is an optionally substituted heterocyclic ring containing at least one nitrogen atom, the point of attachment of the group Y being at a ring nitrogen atom, and n is 0, 1 or 2; R.sup.2 is a group of formula --OSO.sub.2 R.sup.3 wherein R.sup.3 is selected from C.sub.1-8 alkyl, C.sub.1-4 alkyl substituted by an optionally substituted phenyl or heterocyclic ring, C.sub.1-8 haloalkyl, C.sub.2-6 alkenyl, C.sub.2-4 alkenyl substituted by an optionally substituted phenyl or heterocyclic ring, C.sub.2-4 alkynyl, C.sub.2-4 alkynyl substituted by an optionally substituted phenyl or heterocyclic ring, optionally substituted aryl, and a group of formula --N(R.sup.4)(R.sup.5) wherein R.sup.4 and R.sup.5 are independently selected from hydrogen and C.sub.1-6 alkyl or wherein R.sup.4 and R.sup.5 together represent --(CH.sub.2).sub.p -- wherein p is 2, 3, 4 or 5; and wherein the groups R.sup.2 and R.sup.1 occupy either a 1,3 configuration relative to each other on the ring when X is carbon bearing a hydrogen, or a 2,4 or 2,6 configuration relative to the group X when X is nitrogen.The invention also provides compositions comprising the compounds of formula (I) and methods of their use in combating insect pests, and novel intermediates and chemical processes for their preparation.
摘要:
The compounds are guanidines, for example N-benzenesulphonyl-N'-[2-((4-methyl-5-imidazolyl)-methylthio)ethyl]guanidine, which are inhibitors of histamine activity.
摘要:
Hydroxyazepanes display inhibitory activity with respect to glycosidase, with Ki values from-moderate to low micromolar range. Benzyl and 3,6-dibenzyl derivatives of hydroxyazepanes display inhibitory activity with respect to HIV protease. These compounds are synthesized either by chemoenzymatic or chemical methodologies.
