Chinese term (edited): ҩ��ɽ����

I think 药物可接受酯 should be 药学上可接受的酯 or 药理学上可接受的酯, that is, "pharmaceutically acceptable esters". The term "Pharmaceutically acceptable" is frequently used in pharmaceutical patents.

See explanation at: http://www.pharmcast.com/Patents/Yr2003/Jan2003/012803/65116...

“Other possible compounds include pharmaceutically acceptable amides and esters. "Pharmaceutically acceptable ester" refers to those esters which retain, upon hydrolysis of the ester bond, the biological effectiveness and properties of the carboxylic acid and are not biologically or otherwise undesirable.”
