Ligand-Based Design on the Dog-Bone-Shaped BIBR1532 Pharmacophoric Features and Synthesis of Novel Analogues as Promising Telomerase Inhibitors with In Vitro and In Vivo Evaluations

Journal of Medicinal Chemistry, Journal Year: 2022, Volume and Issue: 66(1), P. 777 - 792

Published: Dec. 16, 2022

Telomerase is an outstanding biological target for cancer treatment. BIBR1532 a non-nucleoside selective telomerase inhibitor; however, it experiences ineligible pharmacokinetics. Herein, we aimed to design new BIBR1532-based analogues as promising inhibitors. Therefore, two novel series of pyridazine-linked cyclopenta[b]thiophene (8a-f) and tetrahydro-1-benzothiophene (9a-f) were synthesized. A quantitative real-time polymerase chain reaction was utilized investigate the inhibitory activity candidates. Notably, 8e 9e exhibited best inhibition profiles. Moreover, showed strong antitumor effects against both MCF-7 A549 cell lines. The on cycle apoptosis measured. Besides, evaluated its in vivo using solid Ehrlich carcinoma. reduction tumor weight volume greater than doxorubicin. Also, molecular docking ADME studies performed. Finally, SAR study conducted gain further insights into different potentials upon variable structural modifications.

Anticoagulants as Potential SARS-CoV-2 Mpro Inhibitors for COVID-19 Patients: In Vitro, Molecular Docking, Molecular Dynamics, DFT, and SAR Studies

International Journal of Molecular Sciences, Journal Year: 2022, Volume and Issue: 23(20), P. 12235 - 12235

Published: Oct. 13, 2022

In this article, 34 anticoagulant drugs were screened in silico against the main protease (Mpro) of SARS-CoV-2 using molecular docking tools. Idraparinux, fondaparinux, eptifibatide, heparin, and ticagrelor demonstrated highest binding affinities towards Mpro. A dynamics study at 200 ns was also carried out for most promising anticoagulants to provide insights into dynamic thermodynamic properties compounds. Moreover, a quantum mechanical conducted which helped us attest some findings. biological evaluation (in vitro) compounds performed by carrying MTT cytotoxicity assay crystal violet order assess inhibitory concentration 50 (IC50). It is worth noting that displayed intrinsic potential inhibition with an IC50 value 5.60 µM safety index 25.33. addition, fondaparinux sodium dabigatran showed activities values 8.60 9.40 µM, respectively, indexes 17.60 15.10, respectively. Mpro enzyme investigated utilizing tipranavir as reference standard. Interestingly, attained 2.36 surpassing (IC50 = 7.38 µM) more than three-fold. Furthermore, highly eligible 10.59 µM. Finally, SAR discussed, counting on findings both vitro approaches.

Novel 4-thiophenyl-pyrazole, pyridine, and pyrimidine derivatives as potential antitumor candidates targeting both EGFR and VEGFR-2; design, synthesis, biological evaluations, andin silicostudies

RSC Advances, Journal Year: 2023, Volume and Issue: 13(18), P. 12184 - 12203

Published: Jan. 1, 2023

In this article, we continued our previous effort to develop new selective anticancer candidates based on the basic pharmacophoric requirements of both EGFR and VEGFR-2 inhibitors. Therefore, twenty-two novel 4-thiophenyl-pyrazole, pyridine, pyrimidine derivatives were designed examined as dual EGFR/VEGFR-2 Besides, previously reported antimicrobial activities aforementioned nuclei motivated us screen their antibacterial antifungal well. First, antitumor newly synthesized evaluated against two cancer cell lines (HepG-2 MCF-7). Notably, compounds 2a, 6a, 7a, 10b, 15a, 18a exhibited superior HepG-2 MCF-7 lines. These selected further evaluate anti-EGFR anti-VEGFR-2 potentialities which found be very promising compared erlotinib sorafenib, respectively. Both 10b 2a achieved better inhibition with IC50 values 0.161 0.141 μM 0.209 0.195 μM, Moreover, most active was exact phase cycle arrest investigate mechanism death whether it due apoptosis or necrosis. On other hand, all tested Gram-positive bacteria such S. aureus B. subtilis well Gram-negative E. coli P. aeuroginosa. Also, activity investigated C. albicans A. flavus strains. The findings tests revealed that strong moderate effects. Furthermore, understand pattern by bound site, subjected different docking processes into binding sites. tried correlate compound reference drugs (erlotinib sorafenib) through DFT calculations. Finally, following biological data pyrazole, candidates, concluded a interesting SAR for optimization.
