  • From Celecoxib to a Novel Class of Phosphodiesterase 5 Inhibitors: Trisubstituted Pyrazolines as Novel Phosphodiesterase 5 Inhibitors with Extremely High Potency and Phosphodiesterase Isozyme Selectivity
    作者:Mohammad Abdel-Halim、Sara Sigler、Nora A. S. Racheed、Amr Hefnawy、Reem K. Fathalla、Mennatallah A. Hammam、Ahmed Maher、Yulia Maxuitenko、Adam B. Keeton、Rolf W. Hartmann、Matthias Engel、Gary A. Piazza、Ashraf H. Abadi

    trisubstituted pyrazoline scaffold derived from the COX2 inhibitor, celecoxib, was used to develop novel PDE5 inhibitors. Novel pyrazolines were identified with potent PDE5 inhibitory activity lacking COX2 inhibitory activity. Compound d12 was the most potent with an IC50 of 1 nM, which was three times more potent than sildenafil and more selective with a selectivity index of >10,000-fold against all other PDE
    一种基于配体的方法涉及对源自 COX2 抑制剂塞来昔布的三取代吡唑啉支架进行系统修饰,用于开发新型 PDE5 抑制剂。新型吡唑啉被鉴定为具有有效的 PDE5 抑制活性,但缺乏 COX2 抑制活性。化合物d12是最有效的,其 IC 50为 1 nM,其效力是西地那非的三倍并且更具选择性,选择性指数相对于所有其他 PDE 同工酶 > 10,000 倍。西地那非抑制 PDE5 的全长和催化片段,而化合物d12仅抑制全长酶,表明酶抑制机制不同于西地那非。化合物d12的PDE5抑制活性使用 cGMP 生物传感器测定法在细胞中得到证实。化合物d12的口服给药达到比IC 50值高> 1000 倍的血浆水平,并且在重复给药后没有表现出可辨别的毒性。这些结果揭示了一种以前所未有的效力和同工酶选择性抑制 PDE5 的新策略。

    Major anti-inflammatory agents, steroids and cyclooxygenase, were proved to have serious side effects. Here, a series of chalcone derivatives were synthesized and screened for anti-inflammatory activities. QSAR study revealed that the presence of electron-withdrawing groups in B-ring and electron-donating groups in A-ring of chalcones was important for inhibition of LPS-induced IL-6 expression. Further
    事实证明,主要的抗炎药,类固醇和环氧合酶具有严重的副作用。在这里,合成了一系列查尔酮衍生物,并筛选了抗炎活性。QSAR研究表明,查耳酮的B环中有吸电子基团,而A环中有供电子基团对于抑制LPS诱导的IL-6表达很重要。此外,化合物22,23,26,40,和47抑制TNF-α和IL-6释放的剂量依赖的方式和降低LPS诱导的TNF-α,IL-1β,IL-6,IL-12,和COX-2 mRNA的产生。从机械上讲,化合物23和26干扰JNK /NF-κB信号传导并剂量依赖性地阻止ERK和p38激活。另外,23和26对LPS诱导的死亡显示出显着的保护作用,并且能够阻断巨噬细胞中高葡萄糖激活的细胞因子谱。总之,这些数据显示了一系列在炎性疾病中具有潜在治疗作用的抗炎查耳酮。

Among the screened compounds, 15 was found to be most active as anti-fungal agent (against Rhizoctonia solani, LC50 = 2.36 μg mL−1), 15b was found to be most active anti-bacterial agent (against Klebsiella pneumonia, MIC = 24.68 μg mL−1) and 14b emerged
    合成了基于查尔酮的新型6-乙氧基-2-环己烯-1-酮和2H-吲哚-3-醇衍生物,并使用诸如IR,1 H NMR,13 C NMR,COSY,DEPT和GC-MS等光谱技术对其进行了表征。筛选所有这些化合物的抗真菌,抗细菌和抗氧化活性。通常,环己烯酮衍生物显示出比亲代查尔酮更好的抗真菌和抗菌活性。然而,所有的吲唑衍生物均显示出非常好的抗氧化活性,并且还发现一些具有抗菌活性。在筛选出的化合物中,发现有15种最有效作为抗真菌剂(相对于立枯丝核菌,LC 50  = 2.36μgmL -1),发现15b是最具活性的抗菌剂(针对肺炎克雷伯菌,MIC = 24.68μgmL -1),而14b则是最具活性的抗氧化剂(IC 50  = 19.81μgmL -1)。
