Abstract:
A novel process for preparation of ethyl 2-(4-hydroxy-3-nitrophenyl)-4-methyl-5-thiazolecarboxylate is disclosed. The process involves reaction of ethyl 2-(4-hydroxyphenyl)-4-methyl-5-thiazolecarboxylate with metal nitrate in presence of acid chloride and N,N-Dimethylformamide to produce title compound with improved yield and economics than that reported in the prior art.
Abstract:
The present invention comprises compounds of Formula (I). wherein: X, A 1 , A 2 , A 3 , A 4 , R 1 , R 2 , and R 3 are defined in the specification. The invention also comprises a method of treating or ameliorating a syndrome, disorder or disease, wherein said syndrome, disorder or disease is rheumatoid arthritis or psoriasis. The invention also comprises a method of modulating RORyt activity in a mammal by administration of a therapeutically effective amount of at least one compound of claim 1.
Abstract:
The present invention relates to a compound of formula (I) wherein R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , R 10 , R 11 and G are as defined herein; and wherein the compound of formula (I) is optionally present as an agrochemically acceptable salt thereof. These compounds are suitable for use as herbicides. The invention therefore also relates to a method of controlling weeds, especially grassy monocotyledonous weeds, in crops of useful plants, comprising applying a compound of formula (I), or a herbicidal composition comprising such a compound, to the plants or to the locus thereof.
Abstract:
The present invention relates to novel linkers containing a 2,3-disubstituted succinic group, or 2-monosubstituted, or 2,3-disubstituted fumaric or maleic (trans (E)- or cis (Z) - butenedioic), or acetylenedicarboxyl group for conjugation of a cytotoxic agent, and/or one or more different functional molecules per linker to a cell-binding molecule, through bridge linking pairs of thiols on the cell-binding molecule specifically. The invention also relates to methods of making such linkers, and of using such linkers in making homogeneous conjugates, as well as of application of the conjugates in treatment of cancers, infections and autoimmune disorders.
