Antibacterial activity of structurally diverse natural prenylated isobavachalcone derivatives.

Isobavachalcone (IBC) is a natural prenylated flavonoid containing chalcone and prenyl chain moieties with a wide range of biological and pharmacological properties. In this work, we synthesized structurally diversified derivatives (IBC-2 to IBC-10) from the natural prenylated chalcone IBC isolated from and assessed their antibacterial potency against the Gram-positive and Gram-negative bacterial strains ATCC 29213, ATCC 15187, ATCC25922 and ATCC 27853. IBC and IBC-2 exhibited a minimum inhibition concentration (MIC) of 5.

Identification of Chemical Scaffolds Targeting Drug-Resistant and Latent through High-Throughput Whole-Cell Screening.

Identification of structurally unique chemical entities targeting unexplored bacterial targets is a prerequisite to combat increasing drug resistance against . This study employed a whole-cell screening approach as an initial filter to scrutinize a 10,000-compound chemical library, resulting in the discovery of seven potent compounds with MIC values ranging from 1.56 to 25 μM.

Harnessing host-pathogen interactions for innovative drug discovery and host-directed therapeutics to tackle tuberculosis.

Tuberculosis (TB) is a highly contagious bacterial infection caused by Mycobacterium tuberculosis (Mtb), which has been ranked as the second leading cause of death worldwide from a single infectious agent. As an intracellular pathogen, Mtb has well adapted to the phagocytic host microenvironment, influencing diverse host processes such as gene expression, trafficking, metabolism, and signaling pathways of the host to its advantage. These responses are the result of dynamic interactions of the bacteria with the host cell signaling pathways, whereby the bacteria attenuate the host cellular processes for their survival.

Association between caregiver opposition to topical fluoride and COVID-19 vaccines.

Purpose: Caregivers who oppose topical fluoride in dental settings may be opposed to other preventive health treatments, including COVID-19 vaccines. The study objective was to examine the association between caregiver opposition to topical fluoride and COVID-19 vaccines.

Methods: The study took place at the University of Washington in Seattle, WA.

Nanocrystals: A Deep Insight into Formulation Aspects, Stabilization Strategies, and Biomedical Applications.

Background: Drugs with poor solubility exhibit hurdles in their formulation due to poor dissolution and low bioavailability. Nanocrystallization is a great technique for incorporating poorly soluble drugs and is associated with many benefits.

Objective: The objective of the present review is to discuss formulation techniques for the generation of Nanocrystals (NCs) and illustrate the various advantages of NCs.

Nanocapsules: An Emerging Drug Delivery System.

Background: Controlled drug release and site-specific delivery of drugs make nanocapsules the most approbative drug delivery system for various kinds of drugs, bioactive, protein, and peptide compounds. Nanocapsules (NCs) are spherical shape microscopic shells consisting of a core (solid or liquid) in which the drug is positioned in a cavity enclosed by a distinctive polymeric membrane.

Objectives: The main objective of the present patent study is to elaborate on various formulation techniques and methods of nanocapsules (NCs).

Shear Bond Strength of Glass Ionomer Cement to Silver Diamine Fluoride-Treated Artificial Dentinal Caries.

The purpose of this study was to measure the shear bond strength (SBS) of glass ionomer cement (GIC) to artificial carious dentin with and without silver diamine fluoride (SDF) treatment. Permanent molars were sectioned and demineralized to create artificial carious lesions. In five groups, the demineralization of dentin, application of SDF, use of conditioner, and elapsed time between the placement of SDF and restoration were tested for differences in SBS using an UltraTester machine.

Immunomodulatory Properties of Chitosan: Impact on Wound Healing and Tissue Repair.

Objective: Chitosan, a natural polymer from shelled crustaceans, has been employed in an array of biomedical applications as it possesses a combination of fascinating attributes such as biocompatibility, biodegradability, non-toxicity and ease of chemical alteration into different active derivatives. The ability of chitosan to be tailored into different shapes has made it a very popular polymer for designing novel drug delivery systems for topical, transdermal and gene delivery. Recently, the multifunctional and immunomodulatory properties of chitosan have attracted a lot of attention.

An Appraisal on Various Methods of Nano Particulate Formulations.

Background: Nanotechnology has immense significance in the field of medicine, agriculture, business, public health sector due to wide applicability of the nano products. Basically, nanotechnology is the incorporation of nanoscale structures into larger material components to improve the properties of constructed system.

Method: Nanotechnology serves as an alternative drug delivery system to the liposomes drug delivery system as the stability of the product in biological fluids is the main problem associated with the liposomal drug delivery system.
