Abstract
A physiologically stable thiolate gold(I) derivative [Au(Spyrimidine)(PTA-CH2Ph)]Br has shown inhibition in colon cancer proliferation of Caco-2/TC7, Caco-2/PD7 and HTC-116-luc2 cell lines via apoptotic pathway and S-phase arrest in the cell cycle. Intraperitoneal injection of [Au(Spyrimidine)(PTA-CH2Ph)]Br in athymic nude mice inoculated with HTC-116-luc2 cells prolonged their survival and greatly inhibited tumour growth, near to disappearance. Low concentration of gold in urine and blood were detected in mice after 48 h of administration of 5 mg/kg body weight (bw) of the gold complex and non-organ (kidney and liver) damage has been detected after gold treatment. The results obtained suggested that the thiolate gold(I) derivative shown here could be considered as a candidate for therapeutic treatment in colon cancer.
Keywords: Apoptosis, colon cancer, gold(I), histopathology, in vivo, PTA, Thiolate.

Discovery of Lead compounds targeting transcriptional regulation
Transcriptional regulation plays key physiological functions in body growth and development. Transcriptional dysregulation is one of the important biomarkers of tumor genesis and progression, which is involved in regulating tumor cell processes such as cell proliferation, differentiation, and apoptosis. Additionally, it plays a pivotal role in angiogenesis and promotes tumor ...read more
Induction of cell death in cancer cells by modulating telomerase activity using small molecule drugs
Telomeres are distinctive but short stretches present at the corners of chromosomes that aid in stabilizing chromosomal makeup. The resynthesis of telomeres is supported by the activity of reverse transcriptase ribonucleoprotein complex telomerase. There is no telomerase activity in human somatic cells, but the stem cells and germ cells undergo ...read more
