Abstract
Tumor is one of the leading diseases of today. Chemotherapy and radiation therapy healing chances are limited, so some alternative methods are resorted to. Many papers indicated that garlic and organosulphur compounds diallyldisulphide (DADS) and diallyltrisulphide, which are main components of garlic decrease the cancer risk and inhibit the cell proliferation. In this paper inhibition potency of disulphides (DADS and its synthetic analogues) and trisulphides with different alkyl and phenyl substituents on growth of various tumor (Non-Small cell Lung Cancer, Colon cancer, CNS Cancer, Melanoma, Ovarian Cancer, Renal Cancer, Prostate Cancer, Breast Cancer, Leukemia) cell lines was investigated. Concentration of each compound (DADS, diethyl disulphide, dipropyl disulphide, diphenyl disulphide, tetraethylthiuram disulphide (TETUDS), dimetil trisulphide, dipropyl trisulphide and metilpropyl trisulphide (MPTS) was 10 µmol/L. It was found that DADS has an inhibitory effect on the growth of several cancer cell lines, but synthetic analogues TETUDS and MPTS exhibit stronger effect on certain cells lines. MPTS inhibits the growth of even 12 cell lines for more than 10%, especially leukemia cell line SR and NCI-H522 cell line of Non-Small cell Lung Cancer (reduction of growth for 24% and 47%, resp.). Trisulphide analogues exhibit little higher inhibitory effects in comparison to disulphide ones.
