GC-MS, Antibacterial and In silico Studies of Sudanese Stem Bark Alcoholic Extract.

Introduction: Antimicrobial resistance is a critical global issue, and medicinal plants, as a key source of therapeutic agents, offer potential solutions by offering new antibacterial agents. tree, known as Al Kakamout in Sudan, is a significant source of Gum Arabic and has been traditionally used to treat bacterial diseases. This study aimed to investigate a hydro-ethanol extract of Kakamout stem bark through GC-MS analysis, evaluate its antibacterial activity against two standard bacterial strains, and conduct molecular docking and ADME studies.

Phytochemical constituents, anticancer activity and computational studies of .

The cytotoxic effects of L. aerial part ethanol extract were examined against some cancer cell lines, and HUVEC normal cell lines using MTT assay. The ethanolic extract was prepared by ultrasonic-assisted extraction and analyzed by GC-MS and HPLC.

Discovery of novel potential inhibitors of TMPRSS2 and Mpro of SARS-CoV-2 using E-pharmacophore and docking-based virtual screening combined with molecular dynamic and quantum mechanics.

The pandemic of coronavirus disease is caused by the SARS-CoV-2 which is considered a global health issue. The main protease of COVID 19 (Mpro) has an important role in viral multiplication in the host cell. Inhibiting Mpro is a novel approach to drug discovery and development.

Isolation, Characterization and Quantity Determination of Aristolochic Acids, Toxic Compounds in Aristolochia bracteolata L.

Background: Aristolochic Acids (AAs) are major components of plants in Aristolochia and have been found to be nephrotoxic, carcinogenic and mutagenic. Herein reported are the isolation, identification and quantity determination methods of Aristolochic Acid-I (AA-I) and Aristolochic Acid-II (AA-II) toxic compounds of Aristolochia bracteolata indigenous to Central Sudan and medicinally used in diverse biological functions including analgesic and diuretic effects, treatment of tumors, malaria and/or fevers.

Methods And Results: AAs mixture was extracted with methanol from the defatted material of Aristolochia bracteolata whole plant at room temperature and was isolated from the aqueous methanol extract by chloroform.
