A series of 3,5‐disubstituted‐tetrahydro‐thiadiazine‐2‐thione (1‐16) have been synthesized, characterized by elemental analysis, infrared (IR), UV‐visible, 1H NMR, 13C NMR, and MS spectroscopic techniques, and screened against jack bean urease. Among 16 compounds, compounds (1), (2), (3), (4), (6), (7), and (9) demonstrated excellent ureaseinhibitoryactivity with IC50 values (9.8 ± 0.5, 11.0 ± 0
一系列3,5-二取代的四氢噻二嗪-2-硫酮的(1 - 16)已被合成,通过元素分析,红外(IR),紫外可见,1 H NMR,13 C NMR和MS波谱技巧,并筛选出了防止杰克豆脲酶的方法。在16种化合物中,化合物(1),(2),(3),(4),(6),(7)和(9)表现出优异的脲酶抑制活性,IC 50值为(9.8±0.5,11.0±0.6)分别为16.0±1.5、17.2±0.5、15.4±0.5、19.7±0.4和15.8±0.2μM),甚至比标准硫脲(IC50 = 21±0.01μM)。然而,化合物(8)表现出与标准品几乎相同的抑制水平(IC 50 = 22.9±0.3μM)。在这项工作中,我们首次报道了噻二嗪硫酮的脲酶抑制活性及其分子对接研究。
Thiadiazine thione derivatives as anti-leishmanial agents: synthesis, biological evaluation, structure activity relationship, ADMET, molecular docking and molecular dynamics simulation studies
standard amphotericin B (IC50 = 0.50) and pentamidine (IC50 = 7.52). In order to investigate binding interaction of the most active compounds, molecular docking study was conducted with Leishmania major. Further molecular dynamic simulation study was also carried out to assess the stability and correct binding of the most active compound 10, within active site of the Leishamania major. Likewise, the physiochemical
The new title derivatives (4b—h and 5a—i) were synthesized by reaction of the appropriate primary amine, carbon disulphide, and formaldehyde. These derivatives were prepared in order to study the effects of introducing polar groups at N3 or N5 or at both positions on the biological activity. The compounds were tested for their antifungal activity in vitro against pathogenic (Trichophyton rubrum and
