Discovery of a Potent, Selective Renal Sodium-Dependent Glucose Cotransporter 2 (SGLT2) Inhibitor (HSK0935) for the Treatment of Type 2 Diabetes.

A new class of potent and highly selective SGLT2 inhibitors is disclosed. Compound 31 (HSK0935) demonstrated excellent hSGLT2 inhibition of 1.3 nM and a high hSGLT1/hSGLT2 selectivity of 843-fold.

Rational design, synthesis, and pharmacological properties of pyranochalcone derivatives as potent anti-inflammatory agents.

24 derivatives (5a-x) derived from natural pyranochalcones (I and II) were designed and evaluated for their inhibitory potency on the production of nitric oxide (NO) in LPS-stimulated RAW264.7 cells. Among them, four compounds (5b, 5d, 5f, and 5h) exhibited more potent inhibitory effects on iNOS activity and iNOS-mediated NO production than a positive control indomethacin.

Synthesis and evaluation of 5-benzylidenethiazolidine-2,4-dione derivatives for the treatment of non-alcoholic fatty liver disease.

Twenty-two 5-benzylidenethiazolidine-2,4-dione derivatives (TZDs) were synthesized and evaluated for their potency on adipogenesis of 3T3-L1 adipocytes by measuring the expression of adiponectin protein. Among them, compared to rosiglitazone, 3V was found to upregulate the adiponectin protein expression and downregulate the secretion of leptin protein in 3T3-L1 adipocytes at a respective concentration of 10 µM. With respect to high-fat/high-calorie (HF/HC) diet-induced non-alcoholic fatty liver disease (NAFLD) in Wistar rats, oral administration of 3V could reduce liver weight, visceral fat, and improve serum levels of biochemical markers.

(Z)-5-(4-methoxybenzylidene)thiazolidine-2,4-dione protects rats from carbon tetrachloride-induced liver injury and fibrogenesis.

Aim: To evaluate the hepatoprotective roles of (Z)-5-(4-methoxybenzylidene)thiazolidine-2,4-dione (SKLB010) against carbon tetrachloride (CCl₄)-induced acute and chronic liver injury and its underlying mechanisms of action.

Methods: In the first experiment, rats were weighed and randomly divided into 5 groups (five rats in each group) to assess the protective effect of SKLB010 on acute liver injury. For induction of acute injury, rats were administered a single intraperitoneal injection of 2 mL/kg of 50% (v/v) CCl₄ dissolved in olive oil (1:1).

A novel small molecule, (E)-5-(2,4-di-tert-butyl-6-((2,4-dioxothiazolidin-5-ylidene)methyl)phenyl)-5'-methyl-7,7'-dimethoxy-4,4'-bibenzo[d][1,3]dioxole-5,5'-dicarboxylate (7k), alleviates the development of D-galactosamine/lipopolysaccharide-induced acute liver failure by inhibiting macrophage infiltration and regulating cytokine expression.

Acute liver failure (ALF) is a relatively rare liver disorder that leads to the massive death of hepatocytes. Our previous study reported that a novel small-molecule agent, (E)-5-(2,4-di-tert-butyl-6-((2,4-dioxothiazolidin-5-ylidene)methyl)phenyl)-5'-methyl-7,7'-dimethoxy-4,4'-bibenzo[d][1,3]dioxole-5,5'-dicarboxylate (7k), possessed potent anti-inflammatory activity. In the present study, we further evaluated the therapeutic effects of 7k on lipopolysaccharide (LPS)-induced ALF and investigated the mechanisms of action.

Synthesis and biological evaluation of novel dimethyl[1,1'-biphenyl]-2,2'-dicarboxylate derivatives containing thiazolidine-2,4-dione for the treatment of concanavalin A-induced acute liver injury of BALB/c mice.

In this paper, we reported the synthesis of bifendate derivatives and evaluation of anti-inflammatory activity by detecting the production of the Nitric Oxide (NO) in the lipopolysaccharide(LPS)-stimulated RAW 264.7 cell lines. Among the newly derivatives, compound 7k was the most potent one and two other compounds (7e and 7f) also exhibited greater anti-inflammatory activity than bifendate.

(Z)2-(5-(4-methoxybenzylidene)-2, 4-dioxothiazolidin-3-yl) acetic acid protects rats from CCl(4) -induced liver injury.

Background And Aim: (Z)2-(5-(4-methoxybenzylidene)-2, 4-dioxothiazolidin-3-yl) acetic acid (MDA) is an aldose reductase (AR) inhibitor. Recent studies suggest that AR contributes to the pathogenesis of inflammation by affecting the nuclear factor κB (NF-κB)-dependent expression of cytokines and chemokines and therefore could be a novel therapeutic target for inflammatory pathology. The current study evaluated the in vivo role of MDA in protecting the liver against injury and fibrogenesis caused by CCl(4) in rats, and the underlying mechanisms.

Honokiol crosses BBB and BCSFB, and inhibits brain tumor growth in rat 9L intracerebral gliosarcoma model and human U251 xenograft glioma model.

Background: Gliosarcoma is one of the most common malignant brain tumors, and anti-angiogenesis is a promising approach for the treatment of gliosarcoma. However, chemotherapy is obstructed by the physical obstacle formed by the blood-brain barrier (BBB) and blood-cerebrospinal fluid barrier (BCSFB). Honokiol has been known to possess potent activities in the central nervous system diseases, and anti-angiogenic and anti-tumor properties.

A novel agonist of PPAR-γ based on barbituric acid alleviates the development of non-alcoholic fatty liver disease by regulating adipocytokine expression and preventing insulin resistance.

Non-alcoholic fatty liver disease (NAFLD) is a frequent kind of metabolic syndrome, which included a wide spectrum of liver damage and closely associated with insulin resistance and other metabolic syndromes such as obesity, type II diabetes, hyperglycemia, etc. Recently, a new series of PPARγ ligands based on barbituric acid has been designed, in which 5-(4-(benzyloxy)benzylidene)pyrimidine-2,4,6(1H,3H,5H)-trione (SKLB102) showed a high affinity with PPARγ. The current study aimed to evaluate the protective effect of SKLB102 on NAFLD and investigate the underlying mechanisms.

Improved solubility and pharmacokinetics of PEGylated liposomal honokiol and human plasma protein binding ability of honokiol.

PEGylated liposomal honokiol had been developed with the purpose of improving the solubility and pharmacokinetics compared with free honokiol. Human plasma protein binding ability of honokiol was also investigated. PEGylated liposomal honokiol was prepared by thin film evaporation-sonication method.

Preparation, characterization, pharmacokinetics, and bioactivity of honokiol-in-hydroxypropyl-β-cyclodextrin-in-liposome.

Entrapping inclusion complexes in liposomes has been proposed to increase the entrapment efficiency (EE) and stability of liposomes compared with conventional liposomes. In the present study, a stable honokiol-in-hydroxypropyl-β-cyclodextrin-in-liposome (honokiol-in-HP-β-CD-in-liposome) was developed as honokiol delivery system by a novel method. The final molar ratio of honokiol/HP-β-CD/lipid was selected as 1:2:2.
