Abstract:
Sulfur manifests its influence on platinum anticancer chemotherapy in two aspects: endogenous sulfur-containing molecules such as cysteine, methionine, glutathione, metallothionein and albumin affect the metabolism of platinum drugs and exert adverse effects on the therapeutic efficacy; exogenous congeners such as amifostine (WR-2721) and dimesna (BNP7787) mitigate the toxic side effects of platinum drugs and serve as chemoprotectants. The platinum-sulfur interactions are ubiquitous in the human body and many occurrences encountered during platinum chemotherapy such as uptake, excretion, resistance, and toxicity are related to them. Thus, sulfur-containing molecules play significant roles in the anticancer mechanism of platinum drugs. In this review, the platinum-sulfur interactions are summarized in detail, which may be important for efficient clinical use of the existing platinum agents and beneficial to the rational design of new generation of platinum-based anticancer drugs.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
