Non-small cell lung carcinoma (NSCLC) is a type of lung cancer with the highest prevalence and mortality rate worldwide. Many cases of this type of cancer are overexpression on epidermal growth factor receptor (EGFR). The use of currently available EGFR inhibitors as one of the treatment options for NSCLC still shows various shortcomings, especially the high failure rate of therapy due to resistance. It is important to find NSCLC drug candidates with EGFR inhibitory activity. There are various published articles and it is prominent to draw evidence-based scientific conclusions as a basis of decision-making to select potential compounds for further research. Polymer matrix composites and ScienceDirect are used as a database for article screening. Research using molecular docking method targeted to EGFR with parameters of Gibbs energy and amino acid interactions between ligands and drug targets are included in inclusion criteria. Compounds that achieve docking parameters and have comparable activity to NSCLC guideline drugs are conscientiously ranked. There are only 11 compounds that achieved the docking parameters and had comparable EGFR inhibitory potential. Top-rated compounds include 1,3,5-trisubstituted pyrazoline (3c), 1,3,5-trisubstituted pyrazoline (6c), 1,3,5-trisubstituted pyrazoline (8d), N-(3,4-Dimethylphenyl)-2-[(4-oxo-3-(4-sulfamoylphenyl)-3,4-dihydrobenzo[g] quinazolin-2-yl) thio] acetamide. The top-rated compounds can be used and considered for further research processes.

To address microbial infections and combat drug resistance, we designed, synthesized, and evaluated three novel s-triazine clubbed pharmacophores: 1-acetylpyrazoline (5a-e), 2-aminopyrimidine (6a-e), and 1,5-benzodiazepine (7a-e). These were derived from chalcone (4a-e), showing improved pharmacological profiles. The compounds underwent characterization by FTIR, NMR, and Mass Spectroscopy, and their antimicrobial activities, along with structure-activity relationships (SAR), were assessed using in silico and in vitro methods.

Background: Owing to their extensive utilization as pesticides, heterocycles assume a fundamental role in the management of vector-borne diseases. Despite the presence of numerous heterocyclic compounds in commercial insecticides and larvicides, resistance to pesticides still demands novel strategies to current pest control methods. Considering these facts, this review aims to survey the synthesis and SAR of heterocyclic molecules with larvicidal activity against Aedes aegypti Linn.

STAT3 has emerged as a validated target in cancer, being functionally associated with breast cancer (BC) development, growth, resistance to chemotherapy, metastasis, and evasion of immune surveillance. Previously, a series of compounds consisting of imidazo[1,2-]pyridine tethered 2-pyrazolines (referred to as ITPs) were developed that inhibit STAT3 phosphorylation in estrogen receptor-positive (ER+) BC cells. Herein, a new library of derivatives consisting of imidazo[1,2-]pyridine clubbed 2-pyrazolines (-) and its amide derivatives (-) have been synthesized.

Introduction: In response to continued public health emergency of antimicrobial resistance (AMR), a significant key strategy is the discovery of novel mycobacterial efflux-pump inhibitors (EPIs) as potential adjuvants in combination drug therapy. Interest in identifying new chemotypes which could potentially synergize with the existing antibiotics and can be deployed as part of a combination therapy. This strategy could delay the emergence of resistance to existing antibiotics and increase their efficacy against resistant strains of mycobacterial species.
