Discovery of new VEGFR-2 inhibitors and apoptosis inducer-based thieno[2,3-]pyrimidine.

VEGFR-2 is a key regulator of cancer cell proliferation, migration and angiogenesis. Development of thieno[2,3-]pyrimidine derivatives as potential anti-cancer agents targeting VEGFR-2. Seven and nine studies were conducted.

Design, synthesis, anti-proliferative evaluation, docking, and MD simulation studies of new thieno[2,3-]pyrimidines targeting VEGFR-2.

In this work, new thieno[2,3-]pyrimidine-derived compounds possessing potential anticancer activities were designed and synthesized to target VEGFR-2. The thieno[2,3-]pyrimidine derivatives were tested for their abilities to inhibit VEGFR-2 and to prevent cancer cell growth in two types of cancer cells, MCF-7 and HepG2. Compound 18 exhibited the strongest anti-VEGFR-2 potential with an IC value of 0.

In vitro and in silico evaluation of new thieno[2,3-d]pyrimidines as anti-cancer agents and apoptosis inducers targeting VEGFR-2.

In this study, new thieno[2,3-d]pyrimidine derivatives that could have potential anticancer activity by inhibiting the VEGFR-2 receptor have been designed, synthesized, and investigated. The thieno[2,3-d]pyrimidine derivatives showed strong in vitro abilities to inhibit VEGFR-2 and to prevent cancer cell growth in two different types of cancer cells, MCF-7 and HepG2. Particularly, compound 22 showed the most potent anti-VEGFR-2 activity with an IC value of 0.

New [1,2,4]triazolo[4,3-c]quinazolines as intercalative Topo II inhibitors: Design, synthesis, biological evaluation, and in silico studies.

Fifteen quinazoline derivatives were designed and synthesized as DNA intercalators. The cytotoxicity of the designed members was assessed against HCT-116 and HepG2 cancer cell lines. In addition, the topoisomerase II (Topo II) inhibitory effect was assessed.

Anti-cancer and immunomodulatory evaluation of new nicotinamide derivatives as potential VEGFR-2 inhibitors and apoptosis inducers: and studies.

New nicotinamide derivatives , , , and were designed and synthesised based on the essential features of the VEGFR-2 inhibitors. Compound revealed the highest anti-proliferative activities with IC values of 15.4 and 9.

Discovery of thieno[2,3-d]pyrimidine-based derivatives as potent VEGFR-2 kinase inhibitors and anti-cancer agents.

Vascular endothelial growth factor-2 (VEGFR-2) is considered one of the most important factors in tumor angiogenesis, and consequently a number of anticancer therapeutics have been developed to inhibit VEGFR-2 signaling. Accordingly, eighteen derivatives of thieno[2,3-d]pyrimidines having structural characteristics similar to VEGFR-2 inhibitors were designed and synthesized. Anticancer activities of the new derivatives were assessed against three human cancer cell lines (HCT-116, HepG2, and MCF-7) using MTT.

Design, molecular modeling and anticancer evaluation of thieno[2,3-d]pyrimidine derivatives as inhibitors of topoisomerase II.

Synthesis of 4-(3,5-dimethyl-1H-pyrazol-1-yl)-5,6,7,8-tetrahydrobenzo[4,5]thieno[2,3-d]pyrimidine 1 and its functionalized reactions as nucleophile with various electrophilic reagents were performed through facile methods to yield different cyclic and acyclic derivatives (2-17). The structures of the newly synthesized compounds were established by their elemental analysis and spectral data. Derivatives 4, 14, 16, and 17 in addition to the parent compound 1 had IC at ~4-10 µM against HepG2 and MCF7 and were selected for further investigations.

Novel Tetrahydrobenzo [b] Thiophene Compounds Exhibit Anticancer Activity through Enhancing Apoptosis and Inhibiting Tyrosine Kinase.

Background: Developing new chemotherapeutic agents with molecular targets, larger margin of safety against normal cells and low cost is the target many scientists try to achieve.

Objective: The present study was undertaken to investigate the anticancer activity of a novel series of thiophene compounds and the molecular mechanisms associated.

Method: A series of novel heterocyclic compounds including pyrimidine derivatives (2, 3, 4, 5 8, 11, 12, 13, 14, and 15), thiophene derivatives (6, 7, and 10) and oxoisothiazolidine derivative (9) was synthesized from 4,5,6,7- tetrahydrobenzo[b] thiophene (1).

Synthesis, characterization and molecular docking studies of thiouracil derivatives as potent thymidylate synthase inhibitors and potential anticancer agents.

Thymidylate synthase (TS), one of folate-dependent enzymes, is a key and well-recognized target for anticancer agents. In this study, a series of 6-aryl-5-cyano thiouracil derivatives were designed and synthesized in accordance with essential pharmacophoric features of known TS inhibitors. Nineteen compounds were screened in vitro for their anti-proliferative activities toward HePG-2, MCF-7, HCT-116, and PC-3 cell lines.
