Antidiabetic activity in vitro and in vivo of BDB, a selective inhibitor of protein tyrosine phosphatase 1B, from Rhodomela confervoides

Background and Purpose: Protein tyrosine phosphatase (PTP) 1B (PTP1B) plays a critical role in the regulation of obesity, Type 2 diabetes mellitus and other metabolic diseases. However, drug candidates exhibiting PTP1B selectivity and oral bioavailability are currently lacking. Here, the enzyme inhibitory characteristics and pharmacological benefits of 3-bromo-4,5-bis(2,3-dibromo-4,5-dihydroxybenzyl)-1,2-benzenediol (BDB) were investigated in vitro and in vivo. Experimental Approach: Surface plasmon resonance (SPR) assay was performed to validate the direct binding of BDB to PTP1B, and Lineweaver–Burk analysis of the enzyme kinetics was used to characterise the inhibition by BDB. Both in vitro enzyme-inhibition assays and SPR experiments were also conducted to study the selectivity exhibited by BDB towards four other PTP-family proteins: TC-PTP, SHP-1, SHP-2, and LAR. C2C12 myotubes were used to evaluate cellular permeability to BDB. Effects of BDB on insulin signalling, hypoglycaemia and hypolipidaemia were investigated in diabetic BKS db mice, after oral gavage. The beneficial effects of BDB on pancreatic islets were examined based on insulin and/or glucagon staining. Key Results: BDB acted as a competitive inhibitor of PTP1B and demonstrated high selectivity for PTP1B among the tested PTP-family proteins. Moreover, BDB was cell-permeable and enhanced insulin signalling in C2C12 myotubes. Lastly, oral administration of BDB produced effective antidiabetic effects in spontaneously diabetic mice and markedly improved islet architecture, which was coupled with an increase in the ratio of β-cells to α-cells. Conclusion and Implications: BDB application offers a potentially practical pharmacological approach for treating Type 2 diabetes mellitus by selectively inhibiting PTP1B.

Design, synthesis and biological evaluation of bromophenol-thiazolylhydrazone hybrids inhibiting the interaction of translation initiation factors eIF4E/eIF4G as multifunctional agents for cancer treatment

The eukaryotic initiation factor 4E (eIF4E)is an emerging anticancer drug target for specific anticancer therapy as a promising approach to overcome drug resistance and promote chemotherapy antitumor efficacy. A series of bromophenol-thiazolylhydrazone hybrids were designed, synthesized and evaluated for their antitumor activities. Among of them, the most potent compound 3e (EGPI-1)could inhibit the eIF4E/eIF4G interaction. Further mechanism study demonstrated EGPI-1 played an antitumor role in multiple modes of action including regulating the activity of eIF4E by inhibiting the phosphorylation of eIF4E and 4EBP1, disrupting mitochondrial function through the mTOR/4EBP1 signaling pathway, and inducing autophagy, apoptosis and ROS generation. Moreover, EGPI-1 showed good safety and favorable pharmacokinetic properties in vivo. These observations demonstrate that EGPI-1 may serve as an excellent lead compound for the development of new anticancer drugs that target the eIF4E/eIF4G interface and as a chemical genetic probe to investigate the role of the eIF4E in biological processes and human diseases.
