The first synthesis of the sulfonate analogue of seminolipid, the main sulfoglycolipid in mammalian sperm, is reported. Installation of the sulfonate unit was accomplished by a quite unexplored strategy based on Horner-Wadsworth-Emmons olefination on a 3 '-keto-galactoside, followed by stereoselective double bond reduction.

We report the first in situ reaction of the β-haloketones obtained from laccase catalysed oxidation of secondary alcohol 2-halo phenylethanol's in present study. To the best of our knowledge, this is the first ever fusion of laccase catalysed oxidation reaction with green organic synthetic reaction. The methodology employs molecular oxygen to oxidize secondary alcohol in biphasic medium by laccase from T.

Sulfone motifs play important roles in bioactive compounds and functional materials. The development of efficient methodologies for constructing sulfonyl-containing compounds has thus attracted considerable attention. Here, we introduce a protocol for the preparation of alkyl aryl sulfones under mild conditions.

To develop antibacterial agents with a novel mechanism of action, a series of sulfone compounds containing a 1,2,4-triazolo[4,3-]pyridine were designed and synthesized by progressive molecular structure optimization. The antibacterial activities of some derivatives against the four plant pathogens (), (), (), and () were evaluated. Among them, compound demonstrated significant antibacterial activities against , , and , with EC values of 1.

Background: Venetoclax + azacitidine is a frontline treatment for older adult acute myeloid leukemia (AML) patients and a salvage therapy for relapsed/refractory patients who have been treated with intensive chemotherapy. While this is an important treatment option, many patients fail to achieve complete remission and of those that do, majority relapse. Leukemia stem cells (LSCs) are believed to be responsible for AML relapse and can be targeted through oxidative phosphorylation reduction.

Whole utilization of okara has important economic value, but there are two technical barriers: coarse mouthfeel caused by insoluble dietary fiber (IDF) and undesirable "beany" off-odors. UV-A irradiation and/or microbial fermentation were used to modify okara. The results indicated that single and combined treatments increased the soluble dietary fiber (SDF) content.
