Asymmetric synthesis of the active form of loxoprofen and its analogue
摘要:
The asymmetric synthesis of the active form of the antiinflammatory drug loxoprofen has been reported in this article. Enzymatic kinetic resolution/racemization of a substituted homo-benzylic primary alcohol with lipase-PS, asymmetric alkylation of cyclic ketones using either Enders' or Meyers' strategy followed by a stereoselective biocatalytic reduction of carbonyl group are the key reactions employed successfully to achieve the target molecule and one of its analogue.

Embodiments provide protein-drug conjugates for treatment of cancer. Protein-drug conjugates may include protein-drug conjugates of Formula I: Ctx-L-Cp (I) or a pharmaceutically acceptable salt or solvate thereof, wherein: Ctx is chlorotoxin or a chlorotoxin analog; Cp is a cryptophycin amide, and L is a linker wherein the linker is bound to Ctx at an X2 moiety of the linker and at one of a lysine residue and the N-terminus of the chlorotoxin or chlorotoxin analog.
