The microbial transformation of four Cinchonaalkaloids (quinine, quinidine, cinchonidine, and cinchonine) by endophytic fungi isolated from Cinchona pubescens was investigated. The endophytic filamentous fungus Xylaria sp. was found to transform the Cinchonaalkaloids into their 1-N-oxide derivatives.

The present invention provides stereoselective processes of manufacture for the phosphoramidate nucleotide Compound 1 or a pharmaceutically acceptable salt thereof.
The invention provides:
novel quinidine derivatives of formula
wherein L is a a C1-C10 hydrocarbon linking group which may be straight or branched chain, saturated or unsaturated, and may include from 0 to 3 heteroatoms; and
F is a functional group selected from the group consisting of amino, carboxyl, sulfhydryl, imino, and maleimide,
haptens, immunogens, antibodies and tracers produced from those novel derivatives, and
an improved quinidine fluorescence polarization immunoassay utilizing those antibodies and tracers.
