Environmental influences during early development increase the susceptibility to metabolism diseases in adulthood. Assisted reproductive techniques (ART) expose the gametes or preimplantation embryo to a nonphysiological environment that increases the risk of metabolism diseases in later life. However, the precise underlying causes of ART-related metabolism(More)
Compelling evidence indicates that stress in utero, as manifested by low birth weight (LBW), increases the risk of metabolic syndrome in adulthood. Singletons conceived by assisted reproductive technology (ART) display a significant increase in LBW risk and ART offspring have a different metabolic profile starting at birth. Here, used mouse as a model, we(More)
Histone H3 lysine 9 (H3K9) methylation plays an important role in the regulation of preimplantation embryo development. G9a has been reported to be a major H3K9mono (m1)/dimethylation(m2) methyltransferase and to contain nuclear localization signals. This study was performed to investigate the correlation between H3K9 methylation level and G9a localization(More)
A critical question in natural product-based drug discovery is how to translate the product into drug-like molecules with optimal pharmacological properties. The generation of natural product-inspired scaffold diversity is an effective but challenging strategy to investigate the broader chemical space and identify promising drug leads. Extending our efforts(More)
An efficient redox-amination-aromatization-Friedel-Crafts acylation cascade process from trans-4-hydroxyproline and 2-formylbenzoic acids has been developed for the synthesis of pyrrolo[1,2-b]isoquinolin-10(5H)-ones. Compound 3h was identified as a new potent dual topoisomerase I/II inhibitor.
Human leukocyte antigen (HLA)-G plays a crucial role in conferring fetal-maternal tolerance and ensuring a successful pregnancy. CD56bright natural killer (NK) cells accumulate at the maternal decidua in large numbers during pregnancy and are found in direct contact with fetal trophoblasts. There are increasing evidences that decidual NK (dNK) cells are(More)
p53-MDM2 protein-protein interaction is a promising target for novel antitumor drug development. Previously, we identified a new class of spirotetrahydrothiopyran-oxindole p53-MDM2 inhibitors by novel organocatalytic enantioselective cascade reactions. Herein, a series of new derivatives were designed, synthesized and assayed to investigate the(More)
OBJECTIVES Progress in developing novel rational treatments for rheumatoid arthritis (RA) critically depends on preclinical work in experimental animals. However, there is lack of insight into the most appropriate mode of noninvasive measurement of disease status in experimental RA. This study compared sonography with serum biomarkers in a rabbit model of(More)
Phenotypic screening of high quality compound library is an effective strategy to discover novel bioactive molecules. Previously, we developed the divergent organocatalytic cascade approach to efficiently construct a focused library with scaffold diversity and successfully identified a novel spiropyrazolone antitumor scaffold. Herein, a series of(More)
The normal growth of Rehmannia glutinosa, a widely used medicinal plant in China, is severely disturbed by replant disease. The formation of replant disease commonly involves interactions among plants, allelochemicals and microbes; however, these relationships remain largely unclear. As a result, no effective measures are currently available to treat(More)
