Article Abstract
Aim: To investigate the chemical constituents of tetraploidy Banlangen (Isatis indigotica Fort.).
Methods: Compounds were separated by chromatography on silica gel. Their structures were determined by spectral analysis and chemical evidence.
Results: Three compounds were isolated. Their structures were identified as (E)-2-[(3'-indole) cyanomethylene]-3-indolinone (I), 2-(4-hydroxy-3-methoxyphenyl)-4-[(4-hydroxy-3-methoxy-phenyl)-methyl]-3- hydroxymethyl-tetrahydro-furan (II) and 2-methoxy-4-[tetrahydro-4-[(4-hydroxy-3-methoxy-phenyl)-methyl]-3- hydroxymethyl-2-furanyl] phenyl-1-O-beta-D-glucopyranoside (III).
Conclusion: Compound I is a new compound.

The aim of this study was to investigate the activity of thymoquinone (TQ), carvacrol (CAR) and thymol (TYM) against multi-drug resistant nontuberculous mycobacteria (MDR-NTM), alone and in combination with berberine (BER). Antimicrobial activity was first evaluated at concentrations from 8 to 512 μg/mL. Each of the compounds tested exhibited good activity against nontuberculous mycobacteria (NTM) isolated from fish, with MIC values of 32-128 μg/mL.

Alzheimer's disease (AD) is a prevalent neurological illness that affects over 80% of aged adults globally in cases of dementia. Although the exact pathophysiological causes of AD remain unclear, its pathogenesis is primarily driven by several distinct biochemical alterations: (i) the accumulation of toxic Aβ plaques, (ii) the hyperphosphorylation of tau proteins, (iii) oxidative stress resulting in cell death, and (iv) an imbalance between the two main neurotransmitters, glutamate and acetylcholine (ACh). Currently, there are very few medications available and no treatment.

Background: Plant diseases caused by plant pathogens pose a great threat to biodiversity and food security, and the problem of drug resistance caused by traditional antibiotics and fungicides is becoming more and more serious. It is urgent to develop new antibacterial molecules with low toxicity and high efficiency. Marinoquinoline A is an alkaloid isolated from marine actinomycetes and has a variety of pharmacological activities.
