Transition metal phosphine complex, method for producing same, and anticancer agent containing transition metal phospine complex

摘要

There is provided a novel transition metal phosphine complex having excellent anticancer activity. The transition metal phosphine complex is represented by general formula (1):; (wherein R¹s and R³s each represent an alkyl group, a cycloalkyl group, an aryl group, an aralkyl group, a pyridyl group, or a pyrimidyl group; R²s and R⁴s each represent an alkyl group or a cycloalkyl group, provided that each R¹ and each R² are not the same group and that each R³ and each R⁴ are not the same group; As each represent a linear alkylene group or a cis-vinylene group; M represents a gold atom, a silver atom, a copper atom, or a platinum atom; and B represents an anionic species).
