Special Issue Information

Dear Colleagues,

Targeting kinase pathways has emerged as a promising strategy in the fight against debilitating diseases such as cancer that involve aberrant expression of the kinases and infectious diseases caused by pathogenic microbes such as bacteria, viruses, parasites, or fungi. Targeting protein kinases for cancer treatment has emerged as a successful clinical strategy leading to a reduction in the mortality rate for several cancers. The discovery of the roles of additional protein kinase targets and the development of resistance to existing therapeutics has invigorated research for the development of new potential drug candidates as protein kinase inhibitors to combat cancer.

This Special Issue entitled “Kinase Inhibitors for Anticancer Therapies” will showcase the recent trends in the field of drug discovery of kinase inhibitors, especially for anticancer therapy. In addition, review articles, research articles, and short communications will highlight the efforts of medicinal chemists to propose new molecules endowed with kinase inhibition properties and the strategies to enhance the activity profile of the existing pipeline.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

A series of indolinone-based derivatives were designed and synthesized using the hybrid pharmacophoric design approach as cytotoxic kinase inhibitors. The cytotoxic effects of the designed molecules were tested against MCF-7 and HepG-2 cell lines. Compounds 9 and 20 were the most cytotoxic, with IC50 values against HepG-2 and MCF-7 cells ranging from 2.53 to 7.54 µM. Additionally, compounds 9 and 20 were also found to be slightly more cytotoxic than indirubin with 2.2–2.7-fold higher cytotoxicity with HepG-2 cells. CDK-2 and CDK-4 kinase enzyme inhibition assay showed that compound 9 had a higher inhibitory effect (4.8-fold) than indirubin against CDK-2 and comparable inhibition against CDK-4. Moreover, compound 20 displayed nanomolar inhibitory action against both EGFR kinase and VFGFR-2 enzyme, which were around 8.8- and 5.4-fold higher than the IC50 values of indirubin. Compounds 9 and 20 induced cell cycle arrest at the G1 phase on HepG2 cells. The levels of the key apoptotic proteins assessed revealed elevated levels of the Bax/Bcl-2 ratio, which in turn initiated the caspase3/7 cascade that led to the activation of both intrinsic and extrinsic apoptotic pathways. The cell cycle inhibitory proteins p53 and p21 were significantly upregulated upon treatment with compounds 9 and 20. The docking results revealed that compound 9 exhibits stronger binding affinity to CDK-2 than indirubin, and compound 20 showed a similar binding mode to sorafenib with VEGFR-2. Full article
