Excipients are important components of pharmaceutical preparations that affect their quality, safety, and efficacy. Macrocyclic receptors are a family of supramolecular excipients with several advantages, including molecular-level protection, small sizes,fast kinetics of host-guest recognition, and modular construction. With the continuous advances in the medical field, personalized and precision medicine requires the development of excipients with low dosages, integrated modifying effects, universality,and controlled release. To meet these requirements, we have developed a new family of macrocyclic excipients based on calixarenes by integrating their covalent(broad chemical design space) and noncovalent(wide range of substrates) ***, azocalixarenes(Azo CAs) were designed, showing high binding affinities to a broad spectrum of active pharmaceutical ingredients(APIs), selectivity to interferents, and responsiveness to hypoxic microenvironments. Due to their highly efficient and controllable recognition, Azo CAs serve as low-dose excipients for 30 APIs. Molecular encapsulation by Azo CAs results in the integrated modification of the physicochemical properties of APIs, including solubility, stability, bioavailability,and biocompatibility. Moreover, Azo CAs can be reduced by azoreductases overexpressed in hypoxic microenvironments,leading to the controlled release of APIs. Collectively, Azo CA excipients have broad application prospects for a series of diseases such as enteritis, arthritis, stroke, cancer, bacterial infection and kidney injury, with diverse therapeutic modalities,including chemotherapy, photodynamic therapy, photothermal therapy, immunotherapy, boron neutron capture therapy, radiotherapy, fluorescence imaging, and their combinations.

We report here the synthesis and characterization of two new members of the M2 E 12 family of endohe-dral Zintl clusters,[Fe_(2)Sn_(4)Bi_(8)]^(3-)and[Cr_(2)Sb_(12)]^(3-),both of which contain open-shell metal dimers encap-sulated inside a triple-decker cluster of main-group *** 75-electron[Fe_(2)Sn_(4)Bi_(8)]^(3-)cluster has a D4h-symmetric structure,while[Cr_(2)Sb_(12)]^(3-),despite having the same 75-electron count,is strongly dis-torted to a geometry that resembles a CrSb_(8)crown capped by a CrSb_(4)*** structural differences between the two are driven by the increasing availability of 3d electron density in the earlier transi-tion metal,which leads,ultimately,to different electronic configurations in the two *** trends precisely mirror those observed in the ME_(10)and ME_(12)families containing a single transition metal ion.

This study investigated the therapeutic effects on metabolic syndrome (MetS) and the impact on the intestinal barrier and gut microbiota of Fu brick tea aqueous extracts (FTE) on metabolic syndrome (MetS) in rats fed with a high-fat diet (HFD). Here， the results showed that FTE supplement significantly reduced HFD-induced weight gain， adiposity， dyslipidemia， fasting blood glucose (PBG) increment， and non-alcoholic fatty liver disease (NAFLD). Moreover， FTE supplement resulted in a decline in lipopolysaccharide (LPS) level and attenuation of colonic inflammation and oxidative stress to protect the intestinal barrier function. FTE supplement also maintained the intestinal barrier integrity by improving histological appearance and promoting ZO-1， Occludin， and Claudin-1 protein expression levels. Meanwhile， FTE supplement alleviated the gut microbiota dysbiosis by enhancing the Firmicutes/Bacteroidetes (F/B) ratio and stimulating the colonization of probiotic bacteria such as Akkermansia， Lactobacillus， Adlercreutzia， and Bacteroides. These findings collectively suggest that Fu brick tea could alleviate MetS and Mets-associated traits with the mechanism relevant to the protection of intestinal barrier and gut microbiota regulation.
