- HETEROCYCLIC COMPOUNDS AS INHIBITORS OF MONOACYLGLYCEROL LIPASE (MAGL)
-
The application relates to heterocyclic compounds of the general formula (I), compositions comprising such compounds, a process for preparing these compounds and their medical use. The compounds act as monoacylglycerol lipase (MAGL) inhibitors and are useful in the treatment of neuroinflammation, neurodegenerative diseases, pain, cancer or mental disorders.

- Synthesis and bioactivity of sulfide derivatives containing 1,3,4-oxadiazole and pyridine
-
A series of novel sulfide derivatives containing 1,3,4-oxadiazole and pyridine were synthesized, characterized, and tested for their antibacterial activity against tobacco bacterial wilt and rice bacterial blight and for insecticidal activity toward diamondback moth. The results showed that some compounds had good insecticidal and bactericidal activity, e.g., the activities of compounds 6e and 6g–6j toward tobacco bacterial wilt were much better than those of commercial thiodiazole-copper, and some of the synthesized compounds possessed good insecticidal activity against Plutella xylostella. Compounds 6d, 6h, 6j, 6l, 6p, 6r, and 6p displayed over 93% activity at 500 mg L? 1.

- Design, synthesis, insecticidal activity and 3D-QSR study for novel trifluoromethyl pyridine derivatives containing an 1,3,4-oxadiazole moiety
-
A series of trifluoromethyl pyridine derivatives containing 1,3,4-oxadiazole moiety was designed, synthesized and bio-assayed for their insecticidal activity. The result of bio-assays indicated the synthesized compounds exhibited good insecticidal activity against Mythimna separata and Plutella xylostella, most of the title compounds show 100% insecticidal activity at 500 mg L-1 and >80% activity at 250 mg L-1 against the two pests. Compounds E18 and E27 showed LC50 values of 38.5 and 30.8 mg L-1 against Mythimna separata, respectively, which were close to that of avermectin (29.6 mg L-1); compounds E5, E6, E9, E10, E15, E25, E26, and E27 showed 100% activity at 250 mg L-1, which were better than chlorpyrifos (87%). CoMFA and CoMSIA models with good predictability were proposed, which revealed the electron-withdrawing groups with an appropriate bulk at 2- and 4-positions of benzene ring could enhance insecticidal activity.

- Bioisosteric replacement of central 1,2,4-oxadiazole ring of high affinity CB2 ligands by regioisomeric 1,3,4-oxadiazole ring
-
It has been reported that bioisosteric replacement of an 1,2,4-oxadiazole ring by an 1,3,4-oxadiazole ring leads to higher polarity, reduced metabolic degradation by human liver microsomes and reduced interaction with hERG channels. In a seven to eight st

- Stereoselective synthesis and fungicidal activities of (E)-α- (methoxyimino)-benzeneacetate derivatives containing 1,3,4-oxadiazole ring
-
Fifteen novel (E)-α-(methoxyimino)-benzeneacetate derivatives, the analogues of strobilurins, which contain two pharmacophoric substructures of (E)-methyl methoxyiminoacetate moiety and 1,3,4-oxadiazole ring were stereoselectively synthesized. It was first found that the coupling reaction could give stereoselectively the key intermediate (E) and (Z)-methyl 2-(hydroxyimino)-2-o-tolylacetate 2 with a ratio of 14:1. The preliminary bioassays indicated that all the compounds 1 showed potent fungicidal activity against Rhizoctonia solani, Botrytis cinereapers, Gibberella zeae, Physalospora piricola and Bipolaris mayclis, and all of the tested compounds 1a-1o had more potent fungicidal activities against R. solani than Kresoxim-methyl.
