A series of novel benzothiozinone (BTZ) derivatives were designed, prepared and evaluated for antituberculosis activity. Specifically, the BTZ pharmacophore is retained and the previous heterocyclic ring linker is replaced by alkynyl or vinyl linker, the resulting compounds displayed about 5-fold improved antimycobacterial activity. We further revealed that the linker attached tail group affects the compound metabolic stability, potency and other drug like properties. This work led to the discovery of two compounds (A1 and A11) with acceptable low MICs and improved metabolic stability. The representative compound A11 demonstrated bactericidal efficacy in an acute TB infection mouse model.

Evidence regarding the relationship between free triiodothyronine (FT3) and low-density lipoprotein cholesterol (LDL-C) remains limited. This study aimed to evaluate the association between FT3 and LDL-C levels in patients with type 2 diabetes mellitus (T2DM) who exhibit normal thyroid function. Between June 2022 and October 2023, a total of 3011 inpatients with T2DM and euthyroid status were continuously and non-selectively recruited from a Chinese hospital.

Aquaporin 1 (AQP1) is a key channel for water transport in peritoneal dialysis. Inhibition of AQP1 could therefore impair water transport during peritoneal dialysis. It is not known whether inhibition of AQP1 occurs unintentionally due to off-target interactions of administered medications.

Nanobodies play an increasingly prominent role in cancer imaging and therapy. However, their efficacy is often constrained by inadequate tumor penetration and rapid clearance from the bloodstream, particularly in brain tumors due to the intractable blood-brain barrier (BBB). Glycosylation is a favorable strategy for modulating the biological functions of nanobodies, including permeability and pharmacokinetics, but it also leads to heterogeneous glycan structures, which affect the targeting ability, stability, and quality of nanobodies.

While sulfoximines are nowadays a well established functional group for medicinal chemistry, the properties of sulfilimines are significantly less well studied, and no sulfilimine has progressed to the clinic to date. In this account, the physicochemical and in vitro properties of sulfilimines are reported and compared to those of sulfoximines and other more traditional functional groups. Furthermore, the impact on the physicochemical and in vitro properties of real drug scaffolds is studied in two series of sulfilimine-containing analogs of imatinib and hNE inhibitors.

Conventionally, the size, shape, and biomechanics of cartilages are determined by their voluminous extracellular matrix. By contrast, we found that multiple murine cartilages consist of lipid-filled cells called lipochondrocytes. Despite resembling adipocytes, lipochondrocytes were molecularly distinct and produced lipids exclusively through de novo lipogenesis.
