Harnessing the Sulfur-for-Oxygen Shift: A Magic Bullet for Dynamic Photophysical and Anticancer Activities of Indole-Barbituric Acid Construct.

The development of small molecule-based drugs emerged as a cornerstone of modern drug discovery. Structural activity relationship (SAR) studies in medicinal chemistry are crucial for lead optimization, where a subtle change in the substituent can significantly alter its binding affinity with the biological target. Herein, a highly efficient single-atom substitution (SAS) approach has been developed, where sulfur for oxygen strategy is utilized as a powerful molecular editing technique to identify N-vinyl Indole-thiobarbituric acid (6a) as a novel small molecule-based scaffold with tunable photophysical and antiproliferative activities.

SARS-CoV-2 antibodies in breast milk of women given one & two doses of COVID-19 vaccine.

Background & objectives The COVID-19 pandemic underscores the significance of vaccination in mitigating disease spread, with Covishield and Covaxin serving as pivotal vaccines in India. Breast milk, rich in vital antibodies like IgA and IgG, plays a crucial role in enhancing the immune defence of breastfeeding infants. However, limited research exists on the antibody responses in breast milk among individuals receiving single versus double doses of the COVID-19 vaccine.

Antimicrobial Efficacy of Single-Walled Carbon Nanotubes and Their Combinations Against Enterococcus faecalis Assessed Using the Agar Diffusion Method: An In Vitro Study.

Introduction: This study aimed to evaluate the antimicrobial efficacy of single-walled carbon nanotubes when combined with the commonly used intracanal medicaments by checking their zone of inhibition against .

Materials And Methods: The test materials were divided into five different groups, namely, Group I: single-walled carbon nanotubes; Group II: calcium hydroxide; Group III: chlorhexidine; Group IV: single-walled carbon nanotubes + calcium hydroxide; and Group V: single-walled carbon nanotubes + chlorhexidine. Five sterile Petri plates per group were inoculated with (); wells were made in the plates, one on each side, and a volume of 50 microliters of each solution was dispensed into individual wells using a pipette.

Mitochondria Localized Anticancer Iridium(III) Prodrugs for Targeted Delivery of Myeloid Cell Leukemia-1 (Mcl-1) Inhibitors and Cytotoxic Iridium(III) Complex.

Myeloid cell leukemia-1 (Mcl-1) is an antiapoptotic oncoprotein overexpressed in several malignancies and acts as one of the promising therapeutic targets for cancer. Even though there are several small molecule based Mcl-1 inhibitors reported, the delivery of Mcl-1 inhibitor at the target site is quite challenging. In this regard, we developed a series of mitochondria targeting luminescent cyclometalated iridium(III) prodrugs bearing Mcl-1 inhibitors via ester linkage due to the presence of Mcl-1 protein in the outer mitochondrial membrane.

Comparative Evaluation of Micro-tensile Bond Strength in Non-carious Lesions After Different Pre-surface Treatments.

Background: Non-carious cervical lesions (NCCLs) present themselves as smooth saucer lesions with variable height and depth. Treatment of choice for these lesions should be aimed at conservative management by restoring the teeth. The present study aims to evaluate the micro-tensile bond strength in NCCLs after various surface pre-treatments.
