This review highlights the various structural classes of selective COX-2 inhibitors developed during past seven years with special emphasis on diaryl-hetero/carbo-cyclic class of compounds.
FTIR studies on differential intermolecular association in crystalline and amorphous states of structurally related non-steroidal anti-inflammatory drugs.
Comparison of four crystalline phases though revealed significantly variations, the interactions were remarkably similar in the amorphous state, possibly as a result of constraints of crystal packing ceasing to exist.
