  噻二唑衍生物作为潜在的抗惊厥药

  摘要：

  一系列噻二唑衍生物通过不同取代的苯甲酸环合得到不同取代的噻唑烷-4-酮。元素分析、红外、$^1H$ NMR、$^{13}C$ NMR 和质谱数据证实了合成化合物的结构。这些基团的衍生物通过MES模型评估了它们的抗惊厥活性，并通过旋转棒方法评估了神经毒性。所合成的化合物显示出良好的抗惊厥活性潜力，此外，这些化合物还表现出神经毒性效应。观察发现，相比于具有未取代苯环的化合物[4(a-l)]，在苯环3, 4位带有$OCH_3$的化合物[5(a-l)]对抗惊厥的保护作用较弱。

  A series of thiadiazole derivatives were synthesized with differently substituted benzoic acids which were cyclized to give differently substituted thiazolidin-4-one. Elemental analysis, IR, $^1H$ NMR, $^13}C$ NMR and mass spectral data confirmed the structure of the newly synthesized compounds. The derivatives of these moieties were evaluated for antimicrobial activity. Most of the synthesized compounds showed good antimicrobial activity at 200 and $100\;\mu}g/mL$. Compounds showed most significant antibacterial activity against gram negative test organism Escherichia coli and most significant antifungal activity against test organisms Aspergillus niger and Candida albicans. It was observed that compounds with $OCH_3$ at 3, 4 position of phenyl ring [5(a-l)] were more potent against microbes as compared to compounds having unsubstituted phenyl ring [4(a-l)].

  α‐Glucosidase inhibition is widely used in the oral management of diabetes mellitus (DM), a disease characterized by high blood sugar levels (hyperglycemia) and abnormal carbohydrate metabolism. In this respect, a series of 1,2,3‐triazole‐1,3,4‐thiadiazole hybrids 7a–j were synthesized, inspired by a copper‐catalyzed one‐pot azidation/click assembly approach. All the synthesized hybrids were screened for inhibition of the α‐glucosidase enzyme, displaying IC₅₀ values ranging from 63.35 ± 0.72 to 613.57 ± 1.98 μM, as compared to acarbose (reference) with IC₅₀ of 844.81 ± 0.53 μM. The hybrids 7h and 7e with 3‐nitro and 4‐methoxy substituents at the phenyl ring of the thiadiazole moiety were the best active hybrids of this series with IC₅₀ values of 63.35 ± 0.72 μM, and 67.61 ± 0.64 μM, respectively. Enzyme kinetics analysis of these compounds revealed a mixed mode of inhibition. Moreover, molecular docking studies were also performed to gain insights into the structure–activity‐relationships of the potent compounds and their corresponding analogs.

  摘要α-葡萄糖苷酶抑制剂被广泛应用于糖尿病（DM）的口服治疗，DM是一种以高血糖（高血糖症）和碳水化合物代谢异常为特征的疾病。在这方面，受铜催化的一锅叠氮化/点击组装方法的启发，合成了一系列 1,2,3-三唑-1,3,4-噻二唑杂化物 7a-j。对所有合成的杂交化合物进行了抑制α-葡萄糖苷酶的筛选，结果显示，与 IC50 为 844.81 ± 0.53 μM 的阿卡波糖（参照物）相比，这些杂交化合物的 IC50 值在 63.35 ± 0.72 到 613.57 ± 1.98 μM 之间。在噻二唑分子的苯基环上具有 3-硝基和 4-甲氧基取代基的杂交化合物 7h 和 7e 是该系列中活性最好的杂交化合物，其 IC50 值分别为 63.35 ± 0.72 μM 和 67.61 ± 0.64 μM。对这些化合物的酶动力学分析表明它们具有混合抑制模式。此外，还进行了分子对接研究，以深入了解这些强效化合物及其相应类似物的结构-活性关系。
• Further insight into the dual COX-2 and 15-LOX anti-inflammatory activity of 1,3,4-thiadiazole-thiazolidinone hybrids: The contribution of the substituents at 5th positions is size dependent

  Herin we report the design, synthesis, full characterization and biological investigation of new 15-LOX/COX dual inhibitors based on 1,3-thiazolidin-4-one (15-lipoxygenase pharmacophore) and 1,3,4-thiadiazole (COX pharmacophore) scaffolds. This series of molecular modifications is an extension of a previously reported series to further explore the structural activity relationship. Compounds 3a, 4e, 4n, 4q, 7 and 8 capable of inhibiting 15-LOX at (2.74, 4.2, 3.41, 10.21, 3.71 and 3.36 mu M, respectively) and COX-2 at (0.32, 0.28, 0.28, 0.1, 0.28 and 0.27 mu M, respectively). The results revealed that binding to 15-LOX and COX is sensitive to the bulkiness of the substituents at the 5 positions. 15-LOX bind better with small substituents, while COXs bind better with bulky substituents. Compounds 3a, 4r and 4q showed comparable in vivo anti-inflammatory activity to the reference drug (celecoxib). The ulcer liability test showed no sign of ulceration which ensures the safe gastric profile. Docking study was performed to explore the possible mode of interaction of the new compounds with the active site of human 15-LOX and COX-2. This study discloses some structural features for binding to 15-LOX and COX, thus pave the way to design anti-inflammatory agents with balanced dual inhibition of these enzymes.
