A methine compound represented by the following formula (I): ##STR1## wherein Z.sub.1 and Z.sub.2 each represent a non-metallic atomic group necessitated for forming a five-membered or six-membered, nitrogen-containing heterocyclic ring, R.sub.1 and R.sub.2 each represent an alkyl group, X represents an inorganic anion, k represents a number necessitated for adjusting the electric charge of the molecule to zero, and n represents 0 or 1; with the proviso that when n is 1, the five-membered or six-membered, nitrogen-containing heterocyclic ring formed by Z.sub.2 is cationic, k is not zero and X represents chloride ion. The compound is useful as a spectral sensitizing dye and an antitumor agent.
一种由以下式(I)表示的甲烯化合物:其中Z.sub.1和Z.sub.2分别表示非金属原子团,用于形成含氮五元环或六元环的杂环,R.sub.1和R.sub.2分别表示烷基基团,X表示无机阴离子,k表示调整分子电荷为零所需的数目,n表示0或1;但条件是当n为1时,由Z.sub.2形成的含氮五元环或六元环为阳离子,k不为零且X表示氯离子。该化合物可用作光谱增感染料和抗肿瘤剂。
