The present research was aimed at the synthesis and screening of 35 novel 2-(substituted phenyl imino)-5-benzylidene-4-thiazolidinones having different substitutions at imino phenyl and arylidene groups. The title compounds were synthesized by Knoevenagel condensation at the 5th position of the 4-thiazolidinone ring, in the presence of sodium acetate. The structures were assigned on the basis of spectral

enzyme inhibition. structure–activityrelationshipstudies revealed various structural facets important for the potency of these analogues. The findings revealed a requirement for a nitro group‐including hydrophobic heteroaryl ring for PTP1B inhibition. Molecular dockingstudies afforded good correlation with experimental results. H‐bonding and π–π interactions were responsible for optimal binding and
optical properties (NLO). Further, the biological potential of THZPs was explored in terms of α‐amylase and α‐glucosidaseinhibition. DFT‐based descriptors were calculated to describe the reactivity, and a relationship was developed with biological activities. THZP9 and THZP14 showed remarkable inhibition of α‐amylase and α‐glucosidase with IC50 9.90μM and 4.84μM, respectively, as compared with standard

Synthesis and exploration of configurational dynamics in equilibrating <i>E</i>/<i>Z</i> 2-aryliminothiazolidin-4-ones using NMR and estimation of thermodynamic parameters
2-aryliminothiazolidin-4-ones (3 and 5) were utilized as dynamic chemical systems, whose different states are modulated in a reversible fashion through specific chemical stimuli. The in-depth NMR investigation revealed that the magnitude of rotational energy barrier (ΔG‡) is affected markedly by (1) the solvent polarity; (2) the electronic nature of the ring system present on the exocyclic CN bond and (3) the temperature
在本研究中,2-aryliminothiazolidin-4-ones(3和5)被用作动态化学系统,其不同的状态通过特定的化学刺激以可逆的方式进行调制。深入的 NMR 研究表明,旋转能垒 (Δ G ‡ ) 的大小受 (1) 溶剂极性的显着影响;(2) 存在于环外 C N 键上的环系统的电子性质和 (3) 系统的温度。5-(3-arylallylidene)-2-(arylimino)thiazolidin-4-one 的衍生物在室温下在 DMSO- d 6中以两种异构形式存在: (2 E ,5 Z ,7 E ) ⇆ (2 Z,5 Z ,7 E )。已使用变温动态1 H-NMR (VT DNMR)研究了合成衍生物 ( 5a–5t ) 的立体动力学。为动态过程估计的 Δ G ‡值 (≈15 kcal mol -1 ) 描绘了在环境温度下溶液中两种形式之间的显着障碍。为了更进一步,还进行了线形分析,以清楚地了解平衡机制。
