Design, synthesis, biological and computational screening of novel pyridine-based thiadiazole derivatives as prospective anti-inflammatory agents.

In this study, a novel series of pyridine-based thiadiazole derivatives () were synthesized as prospective anti-inflammatory agents by combining substituted carboxylic acid derivatives of 5-substituted-2-amino-1,3,4-thiadiazole with nicotinoyl isothiocyanate in the presence of acetone. The newly synthesized compounds were characterized by FTIR, H NMR, C NMR, and mass spectrometry. First, the compounds underwent rigorous testing for acute toxicity and anti-inflammatory activity and the results revealed that three compounds-, , and , displayed no acute toxicity and significant anti-inflammatory activity, surpassing the efficacy of the standard drug, diclofenac.

Dengue Virus Entry/Fusion Inhibition By Small Bioactive Molecules: A Critical Review.

Many flaviviruses are remarkable human pathogens that can be transmitted by mosquitoes and ticks. Despite the availability of vaccines for viral infections such as yellow fever, Japanese encephalitis, and tick-borne encephalitis, flavivirus-like dengue is still a significant life-threatening illness worldwide. To date, there is no antiviral treatment for dengue therapy.

Dual Modulators of p53 and Cyclin D in ER Alpha Signaling by Albumin Nanovectors Bearing Zinc Chaperones for ER-positive Breast Cancer Therapy.

CDATA[The inherited mutations and underexpression of BRCA1 in sporadic breast cancers resulting in the loss or functional inactivation of BRCA1 may contribute to a high risk of breast cancer. Recent researchers have identified small molecules (BRCA1 mimetics) that fit into a BRCA1 binding pocket within Estrogen Receptor alpha (ERα), mimic the ability of BRCA1 to inhibit ERα activity, and overcome antiestrogen resistance. Studies indicate that most of the BRCA1 breast cancer cases are associated with p53 mutations.

A New Class of Coumate Benzimidazole Hybrids as BRCA 1 Mimetics Through Unconventional Binding Mode; Synthesis and Preliminary Cytotoxicity Screening.

Background: It was found that breast cancer susceptibility protein 1 (BRCA 1) binds to estrogen receptor alpha (ERα) and inhibits its activity by direct interaction between domains within the amino terminus of BRCA 1 and the carboxy terminus of ER alpha.

Objectives: The present work focuses to identify a new class of BRCA 1 mimetics that work differently from conventional anti-estrogens.

Methods: A novel class of hybrids having coumate and benzimidazolone scaffolds were designed to mimic BRCA 1 protein, suppressing the tumor activity of breast cancer cells.
