The small-molecule drug homoharringtonine targets HSF1 to suppress pancreatic cancer progression.

Heat shock factor 1 (HSF1), an essential transcription factor for stress response, is exploited by various tumors to facilitate their initiation, progression, invasion, and migration. Amplification of HSF1 is widely regarded as an indicator in predicting cancer severity, the likelihood of treatment failure and reduced patient survival. Notably, HSF1 is markedly amplified in 40% of pancreatic cancer (PC), which typically have limited treatment options.

Synthesis and pharmacological validation of fluorescent diarylsulfonylurea analogues as NLRP3 inhibitors and imaging probes.

The NOD-like receptor family pyrin domain-containing protein 3 (NLRP3) is a key cytosolic pattern recognition receptor that senses diverse pathogen- and host-originated threat signals. Aberrant activation of NLRP3 inflammasomes is closely associated with the pathogenesis of various complex inflammatory diseases. Nevertheless, the detailed regulation mechanism of NLRP3 inflammasome and its pathogenic roles in the inflammation progression remain to be fully elucidated.

Two new sesquiterpenoid lactone derivatives from .

Two new sesquiterpenoid lactone derivatives, linderin A () and linderin B () comprising a sesquiterpenoid lactone and a methyl geranylhomogentisate moiety together with six known compounds were isolated from the roots of . Their chemical structures were elucidated using extensive spectroscopic analysis including 1 D, 2 D NMR, and HR-ESI-MS data and compared with previously reported data. The absolute configurations of and were assigned based on the electronic circular dichroism calculation.

Analysis of fecal microbiota in patients with functional constipation undergoing treatment with synbiotics.

This study was performed to identify changes to microbial composition after treatment with synbiotics in patients with functional constipation and to define the key microbiota in the pathogenesis of functional constipation. Fecal samples from 53 patients diagnosed with chronic functional constipation according to the Rome III criteria were analyzed using 16S rRNA sequencing. After treatment with synbiotics for 1 month, fecal samples were collected from 36 patients; after a total of 3 months, fecal samples were collected from 15 patients.

Extraction, preliminary characterization and evaluation of in vitro antitumor and antioxidant activities of polysaccharides from Mentha piperita.

This study describes the extraction, preliminary characterization and evaluation of the in vitro antitumor and antioxidant activities of polysaccharides extracted from Mentha piperita (MPP). The optimal parameters for the extraction of MPP were obtained by Box-Behnken experimental design and response surface methodology (RSM) at the ratio of water to raw material of 20, extraction time of 1.5 h and extraction temperature at 80 °C.

Bioactive saponins from the fruits of Aesculus pavia L.
