found to be an excellent catalytic system for the chemoselective transfer hydrogenation of nitro-compounds to primary amines. Under mild conditions a series of nitro-compounds containing a variety of sensitive functional groups including aldehydes, esters, cyano, and nitrine were reduced to their corresponding amines in good to excellent yields with no byproduct.
Homocamptothecin (hCPT) is a camptothecin (CPT) homologue with the insertion of a methylene (CH2) spacer between the alcohol moiety and carbonyl group of the classical six‐membered α‐hydroxylactone ring. This modification provides higher lactone stability and did not impair its activity against topoisomeraseI (Topo I), but rather appears to improve it compared to CPT. In an attempt to improve the

POPC molecule has a six-fold higher first hyperpolarizability (β0) than urea, which reveals a good optical behaviour of this novel molecule. The optical band gap between the valence band and conduction band has also been measured, and the molecular electrostatic potential has been examined using DFT calculations. The POPC molecule has good drug-likeness properties. Penicillium chryogenum has a good
