Deciphering the sensing of α-amyrin acetate with hs-DNA: a multipronged biological probe.

In this study, we focus on the biomimetic development of small molecules and their biological sensing with DNA. The binding of herring sperm deoxyribonucleic acid (hs-DNA) with naturally occurring bioactive small molecule α-amyrin acetate (α-AA), a biomimetic - isolated from the leaves of () is investigated. Collective information from various imaging, spectroscopic and biophysical experiments provides evidence that α-AA is a minor groove sensor of hs-DNA and preferentially binds to the A-T-rich regions.

Green synthesis of anticancerous honeycomb PtNPs clusters: Their alteration effect on BSA and HsDNA using fluorescence probe.

The screening and characterization of cancer cells has been challenging due to sample insufficiency and extravagant. In this article, we highlighted easy green synthesis of Platinum nanoparticles (PtNPs) in the honeycomb like clusters, and their optical properties (by HRTEM, XRD, DLS, Zeta potential, EDAX, and UV-Visible techniques). PtNPs were responsive of binding mechanisms with the bovine serum albumin (BSA), herring sperm deoxyribonucleic acid (HsDNA) and cytotoxicity of human carcinomas cell.

hsDNA groove binding, photocatalytic activity, and in vitro breast and colon cancer cell reducing function of greener SeNPs.

Selenium nanoparticles (SeNPs) have attracted great attention because of their superior optical properties and wide utilization in biological and biomedical studies. This paper reports an environmentally benign procedure of greener monodispersible SeNP synthesis using the reducing power of Trigonella foenum-graecum extract, characterization and their protective effect against unfolded (Herring sperm DNA) hsDNA. We investigated the anti-cancer activity of SeNPs against MCF-7, MDA MB 435 and COLO-205 cells.
