Abstract
Derivatization of azaarenes can create molecules of biological importance, but reductive functionalization of weakly reactive azaarenes remains a challenge. Here the authors show a dearomative, diastereoselective annulation of azaarenes, via ruthenium(II) reductive catalysis, proceeding with excellent selectivity, mild conditions, and broad substrate and functional group compatibility. Mechanistic studies reveal that the products are formed via hydride transfer-initiated β-aminomethylation and α-arylation of the pyridyl core in the azaarenes, and that paraformaldehyde serves as both the C1-building block and reductant precursor, and the use of Mg(OMe)2 base plays a critical role in determining the reaction chemo-selectivity by lowering the hydrogen transfer rate. The present work opens a door to further develop valuable reductive functionalization of unsaturated systems by taking profit of formaldehyde-endowed two functions.

Heterocyclic androstane and estrane d-ring modified steroids: Microwave-assisted synthesis, steroid-converting enzyme inhibition, apoptosis induction, and effects on genes encoding estrogen inactivating enzymes. J Steroid Biochem Mol Biol 2021; 214:105997.

Abstract
d-ring-fused and d-homo lactone compounds in estratriene and androstane series were synthesized using microwave-assisted reaction conditions. Microwave-irradiated synthesis methods were convenient and effective, and provided high yields with short reaction times. Their inhibition of C17,20-lyase and 17β-hydroxysteroid dehydrogenase type 1 (17β-HSD1) activities were studied in in vitro enzyme assays. d-ring-fused triazolyl estrone analog 24 showed potent inhibition of NADH-complexed 17β-HSD1, with a binding affinity similar to that of the substrate estrone; its inhibition against NADPH-complexed 17β-HSD1 was markedly weaker. Compound 24 also significantly and selectively reduced proliferation of cancer cell lines of gynecological origin. This estrane triazole changed the cell cycle and induced apoptosis of HeLa, SiHa, and MDA-MB-231 cancer cells, measured by both increased subG1 fraction of cells and activation of caspase-independent signaling pathways. A third mode of anti-estrogenic action of 24 saw increased mRNA expression of the SULT1E1 gene in HeLa cells; in contrast, its 3-benzyloxy analog 23 increased mRNA expression of the HSD17B2 gene, thus showing pronounced pro-drug anti-estrogenic activity. Estradiol-derived d-ring triazole compound 24 thus acts at the enzyme, gene expression and cellular levels to decrease the production of active estrogen hormones, demonstrating its pharmacological potential.

Abstract
Fucosylated chondroitin sulfate (fCS) and its depolymerized derivative (DfCS), prepared from sea cucumbers, are well-known for their anticoagulant activity. However, their other functional activities are poorly understood. Recently, we obtained fCS oligosaccharides from Isostichopus Badionotus by a modified controllable Fenton-system, named as DfCS-Ib. The functional activities of these oligosaccharides are still unclear. The present study investigated anti-hyperlipidemic activity of DfCS-Ib using a high-fat diet (HFD)-fed mice model. The results indicated that DfCS-Ib reduced obesity, hyperlipidemia, and inflammation caused by HFD. Meanwhile, DfCS-Ib increased the mRNA expression of PPARγ and decreased the mRNA expression of leptin, aP2, and F4/80 in fat tissue. Transcriptome analysis indicated that DfCS-Ib normalized the expressions of genes regulating lipid metabolism. Our results suggested that DfCS-Ib can alleviated lipid disorder by reducing lipid synthesis and promoting lipid lipidolysis. DfCS-Ib can act as a functional agent to regulate lipid disorder.
