Mechanistic Insights Into Photocatalytic Materials for Toxic Pollutants: Environmental Remediation of Personal Care Products

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Photocatalytic materials have emerged as promising solutions for environmental applications due to their ability to degrade organic pollutants under sunlight or artificial light. In this review, recent progress on the photocatalytic materials used for the degradation of pharmaceutical personal care products (PPCPs) in environmental ...

Unraveling the functional role of the orphan solute carrier, SLC22A24 in the transport of steroid conjugates through metabolomic and genome-wide association studies. [PDF]

open access: yes, 2019
Variation in steroid hormone levels has wide implications for health and disease. The genes encoding the proteins involved in steroid disposition represent key determinants of interindividual variation in steroid levels and ultimately, their effects ...

Pharmacogenetic CYP2B6 variants affect steroid hormone metabolism in human breast cancer cells

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Common genetic CYP2B6 variants correlate with adverse breast cancer outcome. The oestrogen metabolites estriol and 16‐epiestriol, which are formed downstream of CYP2B6‐catalysed 16α/β‐hydroxytestosterone, may be linked to elevated breast cancer risk and might increase due to the demonstrated CYP2B6 variants‐related metabolic shifts.

$\Delta ^{9,11}$-Estrone derivatives as potential antiproliferative agents: synthesis, in vitro biological evaluation and docking studies

open access: yesComptes Rendus. Chimie, 2020
A series of ${\Delta }^{{9,11}}$-estrone derivatives with A- and D-ring modifications has been synthesized and evaluated as antiproliferative agents. The cytotoxicity was assessed in six cell lines (MCF-7, T47-D, LNCaP, HepaRG, Caco-2 and NHDF) by the 3-(

Reprogramming tumor immune microenvironment by ultrasound‐responsive nanoplatforms for enhanced cancer immunotherapy

open access: yesBMEMat, EarlyView.
Ultrasound‐responsive nanoplatforms reprogram the tumor immune microenvironment by targeting tumor cells, immune cells, and non‐immune stromal cells to enhance the efficacy of cancer immunotherapy. Abstract Cancer immunotherapy represents a significant advancement in cancer treatment by enhancing the specific recognition and elimination of cancer cells.

A Sulfuryl Group Transfer Strategy to Selectively Prepare Sulfated Steroids and Isotopically Labelled Derivatives

open access: yesFrontiers in Molecular Biosciences, 2021
The treatment of common steroids: estrone, estradiol, cortisol, and pregnenolone with tributylsulfoammonium betaine (TBSAB) provides a convenient chemoselective conversion of the steroids alcohol/phenol moiety to the corresponding steroidal organosulfate.

Palladium-catalyzed acetylation of arenes. [PDF]

open access: yes, 2014
A simple method for the preparation of aryl methyl ketones is reported. The transformation involves the Pd-catalyzed coupling of an acyl anion equivalent, acetyltrimethylsilane, with aryl bromides to afford the corresponding acetylated arenes in ...

Skeletal Editing from Pyridine to Aniline via C‐Insertion and N‐Isomerization

open access: yesChemistryEurope, EarlyView.
A concise protocol is presented that converts pyridines into anilines by externalizing the original pyridine nitrogen at either the "ipso" or "ortho" position, which results in para or meta‐primary aniline products. A key carbene‐insertion step precedes nitrogen migration, preserving both ring size and overall structure.

Separation and lipophilicity of some new steroid derivatives in normal- and reversed-phase high performance liquid chromatography [PDF]

open access: yesChemical Industry and Chemical Engineering Quarterly, 2011
The separation ability and retention of normal and reversed phase HPLC with, respectively, three non-polar and two polar mobile phases, have been studied by measuring the retention constants of a series of newly synthesized estrone derivatives.
