The present invention relates to a group of conjugates of the hydrophilic polymers and the molecules from boxwood extraction. PEGylation process or the process alike was used to generate the conjugates, which have increased water solubility and prolonged the circulation half-life in the body.
Stereospecificconversion of 9,19-cyclo-4,4,14α-trimethyl-3β-acetoxy-5α,9β-pregnan-20-one, readily accessible from cycloartenol/cyclolaudenol, into three closely related Buxus alkaloids—buxandonine, cyclo-protobuxine-F and cycloprotobuxine-A—is described.
