    摘要: The invention relates to new photolabile coumarinylmethyl esters of cyclic nucleotides of general formula I wherein R1 represents hydrogen, bromine or p-chlorophenylthio R4 represents 7-carboxymethoxy, 6,7-, 5,7- or 7,8-bis-(carboxymethoxy), 7-C1-C3-alkoxycarbonylmethoxy, 6,7-bis(C1-C3-alkoxycarbonylmethoxy), 5,7-bis(C1-C3-alkoxy-carbonylmethoxy), or 7,8-bis(C1-C3-alkoxycarbonylmethoxy), R2 represents —NH2 and R3 is hydrogen (adenine residue), or R2 represents —OH and R3 represents NH2 (guanine residue) The inventive compounds are biologically inactive and exhibit high solubility in aqueous buffer solutions, high efficiency in photocleavage and rapid kinetics of liberation, together with high resistance to solvolysis.
