Nano-Ayurvedic Medicine Approaches Using -Phytochemicals Functionalized Gold Nanoparticles Against Breast Cancer.

Purpose: Breast cancer is a significant global health issue, contributing to 15% of cancer-related deaths. Our laboratory has pioneered a novel approach, combining Ayurvedic principles with green nanotechnology, to develop a scientifically rigorous medical modality referred to as Nano-Ayurvedic Medicine, recently approved by the US Patents and Trademarks Office. Here in we report a new Nano-Ayurvedic medicine agent derived from gold nanoparticles encapsulated with phytochemicals from plant (GB-AuNPs).

Development of a rapid HPLC-fluorescence method for monitoring warfarin metabolites formation: In vitro studies for evaluating the effect of piperine on warfarin metabolism and plasma coagulation.

Warfarin, a widely prescribed anticoagulant, is highly effective for various coagulation disorders. However, its efficacy is limited by a narrow therapeutic index and frequent drug interactions, especially those involving metabolism by Cytochrome P450 (CYP450) enzymes. Piperine, found in black and long pepper, possesses blood-thinning properties and has been observed to inhibit CYP3A and CYP2C enzymes linked to warfarin metabolism.

Functionalized zein nanoparticles targeting neonatal Fc receptor to enhance lung absorption of peptides.

Peptides have a distinguished therapeutic potential for several chronic conditions, and more than 80 peptides exist in the global market. However, most of these marketed peptide drugs are currently delivered intravenously or subcutaneously due to their fast degradation and limited absorption through non-invasive routes. The pulmonary route is favored as a non-invasive route.

Functionalized FcRn-targeted nanosystems for oral drug delivery: A new approach to colorectal cancer treatment.

Colorectal cancer (CRC) is the second type of cancer with the highest lethality rate. The current chemotherapy to treat CRC causes systemic toxicity, unsatisfying response rate, and low tumor-specific selectivity, which is mainly administered by invasive routes. The chronic and aggressive nature of cancers may require long-term regimens.

High Performance Liquid Chromatography (HPLC) with Fluorescence Detection for Quantification of Steroids in Clinical, Pharmaceutical, and Environmental Samples: A Review.

Steroids are compounds widely available in nature and synthesized for therapeutic and medical purposes. Although several analytical techniques are available for the quantification of steroids, their analysis is challenging due to their low levels and complex matrices of the samples. The efficiency and quick separation of the HPLC combined with the sensitivity, selectivity, simplicity, and cost-efficiency of fluorescence, make HPLC coupled to fluorescence detection (HPLC-FLD) an ideal tool for routine measurement and detection of steroids.

Photolytic Controlled Release Formulation of Methotrexate Loaded in Chitosan/TiO Nanoparticles for Breast Cancer.

A new system composed of chitosan nanoparticles loaded with methotrexate (MTX-CS-NPs) and functionalized with photocatalytic TiO nanoparticles (TiO-NPs) was prepared. This system is expected to initiate polymeric rupture of MTX-CS-NPs and subsequently release MTX, upon illumination with UV light. MTX-CS-NPs were prepared and characterized in terms of particle size, charge, polydispersity and drug release before and after coating with TiO-NPs.
