  新型脱氧安息香衍生物的设计，合成及免疫抑制活性

  摘要：

  在寻找具有高功效和低毒性的潜在免疫抑制剂时，合成了一系列新的脱氧安息香素，并对其细胞毒性和免疫抑制活性进行了评估。中合成的化合物，四克脱氧安息香肟（化合物31，32，37，和38）表现出较低的毒性和更高的抑制活性比对其他化合物的抗CD3 /抗CD28共刺激的T细胞增殖。更重要的是，化合物31的细胞毒性比环孢菌素A（CsA）低100倍以上，而且效力更高（31：SI> 684.64，CsA：SI = 235.44）。化合物31的初步抑制机理还通过流式细胞术鉴定了这种化合物，该化合物通过以剂量依赖的方式诱导活化的淋巴结细胞凋亡来发挥免疫抑制活性。另外，通过蛋白质印迹分析检测凋亡的机制。

  Enzymatic Studies of Isoflavonoids as Selective and Potent Inhibitors of Human Leukocyte 5-Lipo-Oxygenase

  摘要：

  Continuing our search to find more potent and selective 5‐LOX inhibitors, we present now the enzymatic evaluation of seventeen isoflavones (IR) and nine isoflavans (HIR), and their in vitro and in cellulo potency against human leukocyte 5‐LOX. Of the 26 compounds tested, 10 isoflavones and 9 isoflavans possessed micromolar potency, but only three were selective against 5‐LOX (IR‐2, HIR‐303, and HIR‐309), with IC50 values at least 10 times lower than those of 12‐LOX, 15‐LOX‐1, and 15‐LOX‐2. Of these three, IR‐2 (6,7‐dihydroxy‐4‐methoxy‐isoflavone, known as texasin) was the most selective 5‐LOX inhibitor, with over 80‐fold potency difference compared with other isozymes; Steered Molecular Dynamics (SMD) studies supported these findings. The presence of the catechol group on ring A (6,7‐dihydroxy versus 7,8‐dihydroxy) correlated with their biological activity, but the reduction of ring C, converting the isoflavones to isoflavans, and the substituent positions on ring B did not affect their potency against 5‐LOX. Two of the most potent/selective inhibitors (HIR‐303 and HIR‐309) were reductive inhibitors and were potent against 5‐LOX in human whole blood, indicating that isoflavans can be potent and selective inhibitors against human leukocyte 5‐LOX in vitro and in cellulo.

  Some pyrogallol and catechol derivatives were synthesized, and their urease inhibitory activity was evaluated by using acetohydroxamic acid (AHA), a well known Helicobacter pylori urease inhibitor, as positive control. The assay results indicate that many compounds have showed potential inhibitory activity against H. pylori urease. 4-(4-Hydroxyphenethyl)phen-1,2-diol (2a) was found to be the most potent

  合成了一些邻苯三酚和邻苯二酚衍生物，并使用众所周知的幽门螺杆菌脲酶抑制剂乙酰氧肟酸（AHA）作为阳性对照，评估了它们对脲酶的抑制活性。测定结果表明许多化合物已显示出对幽门螺杆菌脲酶的潜在抑制活性。已发现4-（4-羟基苯乙基）phen-1,2-二醇（2a）是最有效的脲酶抑制剂，提取分数的IC 50值为1.5±0.2μM，完整细胞的IC 50值为4.2±0.3μM，至少10分别比AHA低2倍和20倍（IC 50为17.2±0.9μM，100.6±13μM）。这一发现表明2a潜在的脲酶抑制剂将值得进一步研究。为了理解所观察到的良好活性，进行了2a到幽门螺杆菌脲酶活性位点的分子对接。

  treatment. As our continuing endeavor to discover isoform and/or mutant selective class of PI3K inhibitors, herein we report the optimization of a structurally novel PI3Kα H1047R mutant inhibitor Hit-02 (EC50 = 115.3 μM), which was identified from a high-throughput screening campaign. Structure-activity relationship analysis enabled us to discover compound 7h, which strongly inhibited PI3Kα H1047R

  磷脂酰肌醇3-激酶α（PI3Kα）是最有吸引力的癌症治疗靶标之一。作为我们不断努力发现PI3K抑制剂的同工型和/或突变体选择性类别的方法，我们在此报告了对结构新颖的PI3KαH1047R突变体抑制剂Hit-02（EC 50  = 115.3μM）的优化，该结构已通过高通量筛选确定活动。结构-活性关系分析使我们能够发现化合物7h，该化合物强烈抑制PI3KαH1047R突变体，其EC 50值为0.55μM ，效力比Hit-02高200倍以上，而对其他PI3K亚型的影响很小。Western blotting检测表明7h降低AKT的磷酸化水平，这是7h抑制PI3KαH1047R突变体功能的另一个证据。细胞活力测定显示7h抑制HCT-116癌细胞的生长，IC 50值为10.9μM。另外，发现7h使细胞周期停滞在G2期，但未显示任何细胞凋亡作用。此外，7h明显诱导细胞自噬，可能有助于其在癌细胞中的抗增

  A number of 2′,3′,4′-trihydroxy-2-phenylacetophenone derivatives were synthesized and examined for growth inhibition of several kinds of bacteria. 2′,3′,4′-Trihydroxy-2-phenylacetophenone itself exhibited no antibacterial activity, but some of its derivatives showed various antibacterial activities depending on functional groups introduced on the 2-phenyl ring. Eighteen out of 24 compounds synthesized in this study appeared to possess antibacterial activities against at least two Gram-positive strains of Bacillus subtilis and Staphylococcus aureus, 2-(biphenyl-4-yl)-2′,3′,4′-trihydroxyacetophenone being the most active with LC50 of 5.8 μm and 5.6 μm respectively. However, none of the synthesized compounds exhibited inhibitory effects on Gram-negative strains, such as Escherichia coli, Proteus mirabilis, Pseudomonas aeruginosa, and Salmonella enterica, suggesting that anti-Gram-positive specificity of the antibacterial compounds.

  研究人员合成了一些 2′,3′,4′-三羟基-2-苯基苯乙酮衍生物，并考察了它们对几种细菌生长的抑制作用。2′,3′,4′-三羟基-2-苯基苯乙酮本身没有抗菌活性，但它的一些衍生物根据在 2-苯基环上引入的官能团的不同而表现出不同的抗菌活性。在本研究合成的 24 种化合物中，有 18 种似乎对至少两种革兰氏阳性菌株枯草杆菌和金黄色葡萄球菌具有抗菌活性，其中 2-（联苯-4-基）-2′,3′,4′-三羟基苯乙酮的活性最高，半数致死浓度分别为 5.8 μm 和 5.6 μm。然而，合成的化合物均未对革兰氏阴性菌株（如大肠杆菌、变形杆菌、铜绿假单胞菌和肠炎沙门氏菌）产生抑制作用，这表明这些抗菌化合物具有抗革兰氏阳性菌的特异性。
