Chitin dipentanoate as the new technologically usable biomaterial.

Mater. Sci. Eng. C. Mater. Biol. Appl. 55 , 50-60, (2015)

In this article, the synthesis of novel biopolymer, chitin dipentanoate (Di-O-Valeryl Chitin, DVCH) has been described. DVCH is a chitin derivative esterified with two valeryl groups at positions 3 and 6 of the N-acetylglucosamine units and it is soluble in c...

Structure-activity relationship of alkyl 9-nitrocamptothecin esters.

Acta Pharmacol. Sin. 24(2) , 109-19, (2003)

To study the structure-activity relationship of alkyl 9-nitrocamptothecin esters.Two alkyl 9-nitrocamptothecin (9NC) esters 5g and 5h were prepared by esterification reactions of 9NC with valeric anhydride and heptanoic anhydride, respectively. Eight 9NC este...
