The present invention describes W-position modified cytidine nucleotides of formula (I). Provided herein are methods of chemical synthesis of ΛΡ-modified cytidine nucleoside triphosphates and their applications as well as uses of the cytidine analogues for the synthesis of modified nucleic acids. The nucleic acid molecule comprises DNA, RNA or a combination of DNA/RNA. One of many applications of modified cytidine nucleotides described herein is enzyme selection, when an enzyme of interest bears an activity of an esterase, amidase, oxidoreductase, lyase, ligase or other enzymatic activity, formula (I) wherein the substituants are as defined in the appended claims.
The invention described herein pertains to selective Janus kinase (JAK) inhibitors and methods of use thereof. Also described are methods for treating diseases involved abnormal JAK/STAT signaling pathway in mammals using the described selective JAK inhibitors or a pharmaceutical formulation thereof.

Blocked mercaptosilanes can be manufactured by reacting mercaptosilanes with organic or inorganic halides or anhydrides in the presence of an acid acceptor and washing the resulting reaction product with water/brine to yield two immiscible phases: an organic phase containing blocked mercaptosilane product and an aqueous phase containing the salt of the acid acceptor. Recycle of the acid acceptor is achieved by adding base to the aqueous phase. The process is suitable to be run in either batch or continuous mode. The blocked mercaptosilane compounds are used as coupling agents in rubber mixtures.
