Pachyphyllanone, a new cycloartane triterpenoid isolated from and its cytotoxic activity.

is a species from the genus (Meliaceae) and the chemical constituent has not been widely explored. A new cycloartane-type triterpenoid, pachyphyllanone (), along with four known compounds (-) were isolated from Miq. Furthermore, the structure of the new compound was elucidated by the interpretation of spectroscopic data, including 1D and 2D-NMR, as well as ECD and NMR calculations (DP4+ analysis).

The Effect of Green-Synthesized Nanoparticles on Dental Caries-Causing Bacteria: A Systematic Review.

Introduction: In this study, a comprehensive search was conducted across multiple databases, including PubMed, Google Scholar, SID, Scopus, Medline, and Web of Science, as well as selected herbal medicine journals. The inclusion of herbal medicine journals was justified by the growing interest in green-synthesized nanoparticles derived from plant extracts, which are relevant to the focus of this review. Articles published between 2015 and 2023 were evaluated.

Relationships of mitochondrial DNA mutations and select clinical diagnoses in perinatally HIV- and ART-exposed uninfected children.

The prevalence of pathogenic mutations within mitochondrial (mt) DNA of youth who were perinatally exposed to HIV and ART but remained uninfected (YHEU) were assessed relative to phenotypic clinical indicators of mitochondrial dysfunction (MtD). This was a cross-sectional, nested case-control study. A total of 144 cases met at least one clinical MtD definition and were matched with up to two controls each (n = 287).

Biallelic potential disease-causing missense variants in TAF1A in two siblings with infantile restrictive cardiomyopathy.

TAF1A, a gene encoding a TATA-box binding protein involved in ribosomal RNA synthesis, is a candidate gene for pediatric cardiomyopathy as biallelic TAF1A variants were reported in two families with affected individuals. Here, we report a third family with two siblings who presented with infantile restrictive cardiomyopathy and carried biallelic missense variants in TAF1A (NM_001201536.1:c.

Immunomodulatory of sesquiterpenoids and sesquiterpenoid dimers-based toll-like receptor 4 (TLR4) from Dysoxylum parasiticum stem bark.

In recent decades, the interest in natural products with immunomodulatory properties has increased due to their therapeutic potential. These products have a wider range of pharmacological activities and demonstrate lower toxicity levels when compared to their synthetic counterparts. Therefore, this study aimed to investigate the immunomodulatory effects of sesquiterpenoids (SQs) and sesquiterpenoid dimers (SQDs) isolated from Dysoxylum parasiticum (Osbeck) Kosterm.
