Synthesis, structure-activity relationship and molecular docking studies of novel quinoline-chalcone hybrids as potential anticancer agents and tubulin inhibitors

Publication date: 15 February 2020Source: Journal of Molecular Structure, Volume 1202Author(s): Salimeh Mirzaei, Farzin Hadizadeh, Farhad Eisvand, Fatemeh Mosaffa, Razieh GhodsiAbstractA new series of quinoline-chalcone hybrids was synthesized. The structures of these compounds were characterized by spectroscopic methods including 1H and 13CNMR and mass spectroscopy. The cytotoxic activity of compounds was evaluated against four human cancer cell lines including A2780 (human ovarian carcinoma) and A2780/RCIS (Cisplatin resistant human ovarian carcinoma), MCF-7 (human breast cancer cells), MCF-7/MX (Mitoxantrone resistant human breast cancer cells) and normal Huvec cells. The structure-activity relationship of synthesized compounds is discussed. Among quinolines 5e, 5g and 5j possessing benzoyl group showed significant cytotoxic activity against both resistant cancer cells and their parents. Compounds 5g and 5j, demonstrated the most antiproliferative activity with IC50 values ranging from 2.32 to 22.4 μM. They were also identified as tubulin inhibitors and induced cell cycle arrest at G2/M phase and apoptosis. Compound 5j induced more arrest at G2/M phase in four cancer cell lines compared to compound 5g. Finally, molecular dynamics simulation and molecular docking studies of compound 5j into the colchicine-binding site of tubulin demonstrated the possible interaction of this compound in the active site of tubulin.Graphical abstract

CONCLUSIONS: The differential diagnosis between OM and primary ovarian cancer can be challenging for the pathologist as well and immunostaining is of help. GCFDP15 is the most specific for breast carcinoma. In contrast with the recent papers published in the literature, we detected TTF-1 cytoplasmic expression in invasive breast carcinoma by SPT24 clone. PMID: 31912104 [PubMed - in process]

In this study, it was confirmed that the PRC1 mRNA and protein expression levels were upregulated in high‑grade serous ovarian carcinoma (HGSOC) tissues, particularly in patients without breast cancer susceptibility gene (BRCA) pathogenic mutations. PRC1 overexpression contributed to drug resistance, tumor recurrence and a poor prognosis. The findings also indicated that PRC1 knockdown decreased the proliferation, metastasis and multidrug resistance of ovarian cancer cells in vitro. It was also demonstrated that forkhead box protein M1 (FOXM1) regulated the mRNA and protein expression of PRC1. Dual‑luciferase repo...

Cowden syndrome (CS) is a multiple hamartoma syndrome associated with the development of various tumors, including endometrial cancer. However, the histology of CS-associated endometrial cancer remains to be fully described. To our knowledge, this is the first report of a patient with CS having endometrial endometrioid carcinoma with ovarian metastasis demonstrating morula-like features. A 31-yr-old, nulliparous, Japanese woman presented with abnormal genital bleeding. Endometrial biopsy revealed endometrioid carcinoma with an extensive morular formation, partially resembling atypical polypoid adenomyoma (APAM). Moreover, ...

PAK5 was primitively detected in the cerebrum and accelerated the filopodia formation in neurocytes. It can reverse the effect of Rho and adjust its activity to mediate maintenance and development of nerve axon by ...
