Abstract
Aim: The aim of our research work is the synthesis of tetrahydroisoquinoline derivatives as anti-Angiogenesis and anti-cancer agents.
Background: Cancer is the second leading cause of deaths in the United States. The current recovery rate from the advanced treatment for the cancer is excessively low. Therefore, the identification of novel, potent, and less toxic anticancer agents remains a top priority.
Objective: To evaluate anti-angiogenesis and anticancer activities of THIQs on different colorectal cancer cell lines (CRC) viz., Colo320, DLD-1, HCT116, SNU-C1, SW480, and GSK3b in pre-treated viability HCT116. and to carry out molecular docking studies of THIQs.
Methods: Twenty synthesized THIQs were screened in the Eli Lilly’s Open Innovation Drug Discovery Program and selected twelve compounds for in vitro primary screening in the KRas (Kirsten rat sarcoma)-Wnt SL (Synthetic Lethal) in the basal viability of different colon cancer cell lines. Docking studies of the active THIQs were also performed in our laboratory, targeting the active sites of KRas and VEGF receptors.
Results: Compound GM-3-18 was found to possess significant activities for KRas inhibition, with IC50 values in the range of 0.9 μM to 10.7 μM, for all colon cancer cell lines. Compound GM-3-121 showed potent anti-angiogenesis activity with IC50 = 1.72 μM. Molecular docking studies showed that the carbonyl oxygen atoms of GM-3-18 and GM-3-121 showed hydrogen bonding interactions with the hydrogen of - OH groups of THR 74 (A).
Conclusion: The results indicated that all the compounds showed moderate to high activity for KRas inhibition. The THIQs bearing the chloro group at the 4-position of the phenyl ring (GM-3-18) exhibited significant KRas inhibition against all colon cancer cell lines.
Keywords: Tetrahydroisoquinoline derivatives (THIQs), KRas, colon cancer, anti-angiogenesis, molecular docking, phenyl ring (GM-3-18).

Discovery of Lead compounds targeting transcriptional regulation
Transcriptional regulation plays key physiological functions in body growth and development. Transcriptional dysregulation is one of 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 metastasis ...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 and aid in stabilizing chromosomal makeup. Resynthesis of telomeres supported by the activity of reverse transcriptase ribonucleoprotein complex telomerase. There is no any telomerase activity in human somatic cells, but the stem cells and germ cells undergone telomerase ...read more
