DihydrofolateReductase (DHFR) Inhibitors: A Comprehensive Review.

Background: Dihydrofolate reductase (DHFR) is an indispensable enzyme required for the survival of most prokaryotic and eukaryotic cells as it is involved in the biosynthesis of essential cellular components. DHFR has attracted a lot of attention as a molecular target for various diseases like cancer, bacterial infection, malaria, tuberculosis, dental caries, trypanosomiasis, leishmaniasis, fungal infection, influenza, Buruli ulcer, and respiratory illness. Various teams of researchers have reported different DHFR inhibitors to explore their therapeutic efficacy.

An overview of nanomaterial based biosensors for detection of Aflatoxin B1 toxicity in foods.

Aflatoxin B1 (AFB1) is one of the most potent mycotoxin contaminating several foods and feeds. It suppresses immunity and consequently increases mutagenicity, carcinogenicity, teratogenicity, hepatotoxicity, embryonic toxicity and increasing morbidity and mortality. Continuous exposure of AFB1 causes liver damage and thus increases the prevalence of cirrhosis and hepatic cancer.

A changing trend in diagnostic methods of Influenza A (H3N2) virus in human: a review.

The influenza virus is classified into four types A, B, C, and D, but type A and B are responsible for major illnesses in people with influenza A being the only virus responsible for flu pandemics due to the presence of two surface proteins called hemagglutinin (H) and neuraminidase (N) on the virus. The two subtypes of influenza A virus, H1N1 and H3N2, have been known to cause many flu pandemics. Both subtypes change genetically and antigenically to produce variants (clades and subclades, also know as groups and subgroups).

Enzymatic inhibitory activity of iridoid glycosides from Picrorrhiza kurroa against matrix metalloproteinases: Correlating in vitro targeted screening and docking.

One specific group of MMPs; gelatinases A (MMP-2) and B (MMP-9) are of precise interest in view of the development and progression of cancer. In the current work, an attempt was made to investigate the enzymatic inhibitory activity of Kutkin (KT), Kutkoside (KS), and Picroside I (PS) by inhibition assay and to further check the downregulation of the expression of mRNA levels of MMP-2 and -9. Further in silico docking studies were performed to investigate the interaction of KT, KS and PS with MMP-2 and MMP-9.
