[Effect of simplified formula of Jinfukang Oral Liquid on apoptosis of renal tubular epithelial cells induced by cisplatin].

In order to study the effect of the simplified formula of Jinfukang Oral Liquid(ALG-12) on renal tubular injury induced by cisplatin(DDP), 48 C57 mice were divided into control group, model group, DDP group, and DDP combined with low, medium, and high dose groups of ALG-12.

[A new idea for studying processing mechanism based on formation of supramolecular aggregates in traditional Chinese medicine decoctions].

Traditional Chinese medicines must be processed into decoction pieces before they can be used medicinally, and decoctions are the most common dosage form in TCM. Recent studies have shown that these decoctions are complex multiphase disperse systems containing supramolecular aggregates. These aggregates form through self-assembly interactions among chemical components du-ring the decocting process, in which hydrogen bonding, π-π interactions, van der Waals' forces, and hydrophobic interactions playing crucial roles.

Biosynthesis of a bacterial meroterpenoid reveals a non-canonical class II meroterpenoid cyclase.

Meroterpenoids are hybrid natural products that arise from the integration of terpenoid and non-terpenoid biosynthetic pathways. While the biosynthesis of fungal meroterpenoids typically follows a well-established sequence of prenylation, epoxidation, and cyclization, the pathways for bacterial perhydrophenanthrene meroterpenoids remain poorly understood. In this study, we report the construction of an engineered metabolic pathway in for the production of the bacterial meroterpenoid, atolypene A (1).

Modified -stabilized Pickering emulsions loaded with the essential oil of Schott: preparation, characterization and evaluation.

Essential oil of Schott (ATEO) have significant biological activity, but their physical and chemical properties are unstable and susceptible to interference by external factors, resulting in oxidation, decomposition, and isomerization of essential oils (EOs), ultimately diminishing the quality of EOs and escalating clinical risks. In this research, based on the concept of " combination of medicine and adjuvant, " the unsuitable stabilizer in Lingzhu powder prescription was modified with a SiO surface to become a stabilizer suitable for Pickering emulsion. The modified was synthesized, with a focus on exploring the surface modification of to facilitate its role as a stabilizer in Pickering emulsion.

Early-stage biosynthesis of phenalinolactone diterpenoids involves sequential prenylation, epoxidation, and cyclization.

The chemical logic associated with assembly of many bacterial terpenoids remains poorly understood. We focused our efforts on the early-stage biosynthesis of the phenalinolactone diterpenoids, demonstrating that the -perhydrophenanthrene core is constructed by sequential prenylation, epoxidation, and cyclization. The functions and timing of PlaT1-PlaT3 were assigned by comprehensive heterologous reconstitution.

Natural triterpenoid-aided identification of the druggable interface of HMGB1 occupied by TLR4.

HMGB1 interacts with TLR4 to activate the inflammatory cascade response, contributing to the pathogenesis of endogenous tissue damage and infection. The immense importance of HMGB1-TLR4 interaction in the immune system has made its binding interface an area of significant interest. To map the binding interface of HMGB1 occupied by TLR4, triterpenoids that disrupt the HMGB1-TLR4 interaction and interfere with HMGB1-induced inflammation were developed.

Shape memory and self-healing in a molecular crystal with inverse temperature symmetry breaking.

Mechanically responsive molecular crystals have attracted increasing attention for their potential as actuators, sensors, and switches. However, their inherent structural rigidity usually makes them vulnerable to external stimuli, limiting their usage in many applications.

Inclusion complex of quercetin with sulfobutylether β-cyclodextrin: preparation, characterization, antioxidant and antibacterial activities and the inclusion mechanism.

Quercetin (QCT) has a variety of pharmacological effects, such as antioxidant, antibacterial, anticancer, anticardiovascular and antiaging effects. However, its poor water solubility, stability and bioavailability limit its applications. The special structure of cyclodextrins and their derivatives with a hydrophobic inner cavity and hydrophilic outer wall can load a variety of hydrophobic drugs of a suitable size and shape, thereby improving the stability and solubility of these molecules.

[Improvement of solubility of epimedium flavonoid secondary glycoside components by traditional Chinese medicine polysaccharides and its mechanism].

The poor solubility of insoluble components of traditional Chinese medicine(TCM) is an important factor restricting the development of its preparations. Natural polysaccharides of TCM can be used as functional components to increase the solubility of insoluble components. Epimedium flavonoid secondary glycoside components(EFSGC) have been shown to have positive effects on the prevention and treatment of osteoporosis, but they exhibit poor solubility.

Structure-guided optimisation of -hydroxythiazole-derived inhibitors of factor inhibiting hypoxia-inducible factor-α.

The human 2-oxoglutarate (2OG)- and Fe(ii)-dependent oxygenases factor inhibiting hypoxia-inducible factor-α (FIH) and HIF-α prolyl residue hydroxylases 1-3 (PHD1-3) regulate the response to hypoxia in humans catalysing hydroxylation of the α-subunits of the hypoxia-inducible factors (HIFs). Small-molecule PHD inhibitors are used for anaemia treatment; by contrast, few selective inhibitors of FIH have been reported, despite their potential to regulate the hypoxic response, either alone or in combination with PHD inhibition. We report molecular, biophysical, and cellular evidence that the -hydroxythiazole scaffold, reported to inhibit PHD2, is a useful broad spectrum 2OG oxygenase inhibitor scaffold, the inhibition potential of which can be tuned to achieve selective FIH inhibition.

Design, synthesis and biological evaluation of tetrahydroquinoxaline sulfonamide derivatives as colchicine binding site inhibitors.

Colchicine binding site inhibitors (CBSIs) are potential microtubule targeting agents (MTAs), which can overcome multidrug resistance, improve aqueous solubility and reduce toxicity faced by most MTAs.

Catalytic asymmetric indolization by a desymmetrizing [3 + 2] annulation strategy.

A new catalytic asymmetric indolization reaction by a desymmetrizing [3 + 2] annulation strategy is developed. The reaction proceeds a rhodium-catalyzed enantioposition-selective addition/5--trig cyclization/dehydration cascade between -amino arylboronic acids and 2,2-disubstituted cyclopentene-1,3-diones to produce -unprotected cyclopenta[]indoles bearing an all-carbon quaternary stereocenter in high yields with good enantioselectivities. A quantitative structure-selectivity relationship (QSSR) model was established to identify the optimal chiral ligand, which effectively controlled the formation of the stereocenter away from the reaction site.
