Overview

Titanocene dichloride is an organotitanium compound with the formula (η^5-C5H5)2TiCl2, commonly abbreviated as Cp2TiCl2. It is a red to red-orange crystalline solid that slowly hydrolyzes in air and decomposes in water. Titanocene dichloride was the first non-platinum coordination complex and the first metallocene to undergo clinical trials as an anticancer agent. Its mechanism of action differs from platinum-based drugs like cisplatin; while cisplatin binds preferentially to DNA bases (N7 of guanine), titanocene dichloride exhibits higher affinity for the phosphate backbone of DNA and can also bind transferrin after hydrolysis in aqueous environments. It has shown activity against cisplatin-resistant cancer cells in vitro and was investigated primarily for its antitumor properties but development was discontinued after phase 2 trials[4][5][6][7]. Besides its experimental use as a chemotherapeutic agent, it is widely used as a reagent in organometallic chemistry and organic synthesis.
