NOVEL CYCLOSAL NUCLEOTIDES WITH REDUCED INHIBITORY POTENCY TOWARD HUMAN BUTYRYLCHOLINESTERASE
摘要:
Two novel cycloSal-d4T monophosphates (d4TMPs) with increased steric demand have been synthesized via a new synthetic route. While 3-cyclohexyl-cycloSal d4TMP did not show a significantly reduced inhibitory potency toward human butrylylcholinesterase, the opposite was the case for the second novel pronucleotide, bi-(cycloSal-d4TMP).
An extension of the cycloSal-pronucleotide approach is presented. Attachment of an enzyme-cleavable ester/acylal group to the cycloSal-d4TMP triesters should allow these compounds to be trapped intracellularly after cleavage. The ester/acylal groups were introduced in the 3- or 5-position of the cycloSal ring system, and surprising differences were observed in hydrolysis studies in CEM cell extracts

Help your neighbor: A new chlorohydrosilane can reduce aromatic aldehydes when assisted by an ortho‐phenol moiety and upon activation by a Lewis base. This metal‐free reductive method was observed to be regio‐ and chemoselective as other carbonyl functionalities in the same molecule are not reduced.

compounds was designed, synthesized and evaluated as cholinesterase inhibitors. The biological assay experiments showed that most of the compounds displayed a clearly selective inhibition for butyrylcholinesterase (BChE), while a weak or no effect towards acetylcholinesterase (AChE) was detected. Among these benzofuran derivatives, compound 16 exhibited the highest BChE inhibition with an IC50 value
