- Synthesis of 1,3,4-oxadiazoles as promising anticoagulant agents
-
In the present study, a series of 2,5-disubstituted-1,3,4-oxadiazole derivatives (4a-4k) were designed and subjected to molecular docking simulation studies onto the enzymes vitamin K epoxide reductase (PDB: 3KP9) and factor Xa (PDB: 1NFY) to visualize their binding affinity towards the said target proteins. In silico ADME studies highlighted that the designed compounds are safe enough and have the potential to be considered as drug like molecules, indicating the appreciable ADME property & probable toxicity of the designed compounds. The title compounds were synthesized from (benzo[d]oxazol-2-yl)methanamine and evaluated for in vitro radical scavenging properties and ex vivo anticoagulant activity. The results of the ex vivo anticoagulant evaluation highlighted that the compounds exhibited a significant increase in prothrombin time and clotting time, and a minimal increase in the activated partial thromboplastin time, indicating that the compounds can be considered for promising anticoagulant therapy. The results of the radical scavenging experiments indicated that the compounds have substantial antioxidant activity.

- Method for synthesizing benzoxazole through microwave radiation of benzamide compound in water phase
-
The invention discloses a method for synthesizing benzoxazole through microwave radiation of a benzamide compound in a water phase. The benzamide compound is added into the water phase under the microwave condition to be subjected to a cyclization reaction for generating the benzoxazole under the alkali condition, and the method for preparing the benzoxazole is environmentally friendly, easy and convenient to operate, safe, low in cost and efficient. Compared with the prior art, the method can be applied to a large number of functional groups, the yield is high, the number of by-products is small, and the method is easy to operate, safe, low in cost and environmentally friendly. (Please see the specifications for the formula).

- Role of benzimidazole (Bid) in the δ-opioid agonist pseudopeptide H-Dmt-Tic-NH-CH2-Bid (UFP-502)
-
H-Dmt-Tic-NH-CH2-Bid (UFP-502) was the first δ-opioid agonist prepared from the Dmt-Tic pharmacophore. It showed interesting pharmacological properties, such as stimulation of mRNA BDNF expression and antidepression. To evaluate the importance of 1H-benzimidazol-2-yl (Bid) in the induction of δ-agonism, it was substituted by similar heterocycles: The substitution of NH(1) by O or S transforms the reference δ-agonist into δ-antagonists. Phenyl ring of benzimidazole is not important for δ-agonism; in fact 1H-imidazole-2-yl retains δ-agonist activity.
