Phase 1 clinical trial evaluating safety, bioavailability, and gut microbiome with a combination of curcumin and ursolic acid in lipid enhanced capsules.

As screening strategies employ better biomarkers and genetics to identify individuals at an increased risk of prostate cancer, there are currently no chemotherapeutic prevention strategies. With any chemoprevention strategy, the population will be younger and healthier; therefore, they will be less tolerant of side effects. This study translated findings from screening a natural product library and pre-clinical evaluation of curcumin (CURC) in combination with ursolic acid (UA) in prostate cancer models.

A novel mesna-based electrochemical sensor embellished with silver nanoparticles for ultrasensitive analysis of modafinil.

Modafinil (MOD) is a CNS stimulant used for the treatment of narcolepsy, shift work sleep disorder, excessive daytime sleepiness, and post-COVID 19 neurological symptoms. In the literature, there is no report of square wave voltammetric (SWV) methods being used for the determination of MOD. This study describes, for the first time, the construction and evaluation of the analytical performance of a novel sensor for ultrasensitive SWV detection of MOD.

Enzymatic depletion of l-Met using an engineered human enzyme as a novel therapeutic strategy for melanoma.

Many cancers, including melanoma, have a higher requirement for l-methionine in comparison with noncancerous cells. In this study, we show that administration of an engineered human methionine-γ-lyase (hMGL) significantly reduced the survival of both human and mouse melanoma cells in vitro. A multiomics approach was utilized to identify global changes in gene expression and in metabolite levels with hMGL treatment in melanoma cells.

Development and validation of a novel evaporation setup-assisted TLC method with fluorescence detection for determination of flibanserin in pharmaceutical and biological samples.

A specific and sensitive thin layer chromatographic method coupled with fluorescence detection for determination of flibanserin (FLN) that treats woman hypoactive sexual desire disorder was developed. The proposed method depends on the enhancement of FLN native fluorescence intensity via the exposure of the developed TLC plate to concentrated hydrochloric acid vapors. Herein, an evaporation setup needed for HCl vapors exposure step was designed for the first time to ensure a uniform distribution of the vapors throughout the developed bands on the plate.

Towards understanding of the interaction of certain carbapenems with protein via combined experimental and theoretical approach.

The interactions of the recent carbapenems; ertapenem (ERP) and meropenem (MRP); with serum albumin (SA) were closely investigated by a combined spectrofluorometric experimental and theoretical approach. The approach is based on the quenching of fluorescence intensity of bovine serum albumin (BSA) upon binding with different carbapenems. The quenching was observed at λ 333-340 nm after excitation at 280 nm.

Poly (bromocresol green) flakes-decorated pencil graphite electrode for selective electrochemical sensing applications and pharmacokinetic studies.

A square wave voltammetric method for selective determination of meropenem (MRP) and ertapenem (ERP) was developed using pencil graphite electrode modified with poly (bromocresol green) (PGE/PBCG). The modified electrode film was characterized by scanning electron microscopy and electro-chemical impedance spectroscopy. Under the optimized conditions, the prepared electrode has good linearity over concentration range 1.
