摘要:
The invention relates to novel, photo-labile cumarinylmethyl esters of cyclic nucleotides of general formula (I): axial isomer (Ia), equatorial isomer (Ib); wherein R1 represents hydrogen, bromine or p-chlorophenylthio, R4 represents 7-carboxymethoxy, 6,7-, 5,7- or 7,8- bis(car-boxymethoxy), 7-C¿1?-C3-alkoxycarbonylmethoxy, 6,7-bis(C1-C3-alkoxycarbonylmethoxy), 5,7-bis(C1-C3-alkoxycarbonylmethoxy) or 7,8-bis(C1-C3-alkoxy-carbonylmethoxy), R?2¿ represents -NH¿2? and R?3¿ is hydrogen (adenine radical) or R2 denotes -OH and R3 denotes -NH¿2? (guanine radical). The inventive compounds are biologically inactive and have a high solvolysis resistance, exhibiting high solubility in aqueous buffer solutions, high photocleavage and quick release kinetics.
