Bromodomain and extra-terminal (BET) is a promising therapeutic target for various hematologic cancers. We used the BRD4 inhibitor compound 13 as a lead compound to develop a variety of compounds, and we introduced diverse groups into the position of the compound 13 orienting toward the ZA channel. A series of compounds (14–23, 38–41, 43, 47–49) bearing triazolopyridazine motif exhibited remarkable BRD4 protein inhibitory activities. Among them, compound 39 inhibited BRD4(BD1) protein with an IC50 of 0.003 μM was superior to lead compound 13. Meanwhile, compound 39 possess activity, IC50 = 2.1 μM, in antiproliferation activity against U266 cancer cells. On the other hand, compound 39 could arrest tumor cells into the G0/G1 phase and induce apoptosis, which was consistent with its results in inhibiting cell proliferation. Biological and biochemical data suggest that BRD4 protein might be a therapeutic target and that compound 39 is an excellent lead compound for further development.

The free fatty acid receptor 1 (FFA1 or GPR40) and peroxisome proliferator-activated receptor δ (PPARδ) have attracted a lot of attention due to their role in promoting insulin secretion and sensibility, respectively, which are two major features of diabetes. Therefore, the dual FFA1/PPARδ agonists would increase insulin secretion and sensibility by FFA1 and PPARδ activation. In this study, we hybrid FFA1 agonist AM-4668 with PPARδ agonist GW501516, leading to the identification of orally bioavailable dual agonist 32, which revealed high selectivity over other PPARs. Moreover, compound 32 exhibited good pharmacokinetic profiles with high plasma concentration, sustained half-life and low clearance in vivo. During the hypoglycemic test, a dual agonist 32 enhanced the tolerance of ob/ob mice for glucose loading in a dose-dependent manner. Our results suggest that dual FFA1/PPARδ agonist could be a valuable therapy for type 2 diabetes.

The free fatty acid receptor 1 (FFA1/GPR40) has attracted interest as a novel target for the treatment of type 2 diabetes. Several series of FFA1 agonists including TAK-875, the most advanced compound terminated in phase III studies due to concerns about liver toxicity, have been hampered by relatively high molecular weight and lipophilicity. Aiming to develop potent FFA1 agonists with low risk of liver toxicity by decreasing the lipophilicity, the middle phenyl of TAK-875 was replaced by 11 polar five-membered heteroaromatics. Subsequently, systematic exploration of SAR and application of molecular modeling, leads to the identification of compound 44, which was an excellent FFA1 agonist with robustly hypoglycemic effect both in normal and type 2 diabetic mice, low risks of hypoglycemia and liver toxicity even at the twice molar dose of TAK-875. Meanwhile, two important findings were noted. First, the methyl group in our thiazole series occupied a small hydrophobic subpocket which had no interactions with TAK-875. Furthermore, the agonistic activity revealed a good correlation with the dihedral angle between thiazole core and the terminal benzene ring. These results promote the understanding of ligand-binding pocket and might help to design more promising FFA1 agonists.

A series of new analogs based on the structure of lead compound 10 were designed, synthesized and evaluated for their in vitro anti-cancer activities against four selected human cancer cell lines (HL-60, Bel-7402, SK-BR-3 and MDA-MB-468). Several synthesized compounds exhibited improved anti-cancer activities comparing with lead compound 10. Among them, 1,3,4-oxadiazole analogs 17o showed highest bioactivity with IC50 values of 1.23, 0.58 and 4.29 μM against Bel-7402, SK-BR-3 and MDA-MB-468 cells, respectively. It is noteworthy that 17o has potent anti-proliferation activity toward a panel of cancer cells with relatively less cytotoxicity to nonmalignant cells. The further mechanistic study showed that it induced apoptosis and cell cycle arrest through disrupting spindle assembly in mitotic progression, indicating these synthesized dithiocarbamates represented a novel series of anti-cancer compounds targeting mitosis.

The reactivity of ketene dithiolates in the presence of different equivalents of sodium ethoxide was studied. 2-(Bis((5-aryl-1,3,4-oxadiazol-2-yl) methylthio)methylene)malononitriles 5 and 2-(bis((5-aryl-1,3,4-thiadiazol-2-yl) methylthio)methylene)malononitriles 6 were prepared by the reaction of malononitrile with carbon disulfide and 5-aryl-2-(chloromethyl)-1,3,4- oxadiazoles 3/5-aryl-2-(chloromethyl)-1,3,4-thiadiazoles 4. The preliminary antimicrobial and antioxidant activities of the lead compounds were assayed.
