  摘要：

  A series of derivatives of 3-benzyl-2H-benzoxazine-2,4(3H)-dione substituted in positions 6, 7 or 8 on the benzoxazine, and in positions 3 or 4 on the benzyl moiety was synthesized. The compounds were evaluated for in vitro antimycobacterial activity against Mycobacterium avium and two strains of Mycobacterium kansasii. The disadvantage of the compounds is in their low solubility in water. The antimycobacterial activity of N-benzylsalicylamides correlates with that of 3-benzyl-2H-1,3-benzoxazin-2,4(3H)-diones and depends on the partition coefficients and electronic indexes.

  On the Relationship between the Structure and Antimycobacterial Activity of Substituted N-Benzylsalicylamides

  摘要：

  六十六种在酰基部位3、4或5以及苄芳香环上的位置4处取代的N-苄基水杨酰胺被合成。这些化合物被测试其对结核分枝杆菌、堪萨斯分枝杆菌和埃维分枝杆菌的体外抗结核活性。为了评估结构-抗结核活性关系（QSARs），采用了基于Free-Wilson方法以及Free-Wilson和Hansch方法的组合方法（取代基常数用于描述苄基取代基的影响，指示参数用于酰基部位的取代基）。对于苄基取代基，使用Hammett常数对于QSAR方程并不重要。脂溶性参数（π^2）的二次表示仅在抗结核活性对埃维分枝杆菌的QSAR方程中显著。

  Sixty-six N-benzylsalicylamides substituted in the acyl moiety in positions 3, 4 or 5 and in position 4 on the benzylic aromatic ring were synthesized. The compounds were tested for in vitro antimycobacterial activity against Mycobacterium tuberculosis, Mycobacterium kansasii and Mycobacterium avium. To evaluate structure-antimycobacterial activity relationships (QSARs), approaches based on the Free-Wilson as well as a combination of the Free-Wilson and Hansch methods were employed (substituent constants were used to describe the influence of the benzyl substituents, indicator parameters were used for the substituents on the acyl moiety). The use of the Hammett constants for benzyl substituents was not important for QSAR equations. The quadratic representation of lipophilicity parameters (π²) was significant only in QSAR equations of antimycobacterial activity against M. avium.

  Inhibition of photosynthetic electron transport (PET) in spinach chloroplasts by sixty-one ring-substituted N-benzylsalicylamides was investigated. The inhibitory potency of the compounds expressed by IC50 value varied from 2.0 to 425.3 μmol/L. Several evaluated compounds can be considered as effective PET inhibitors; these include N-(3,4- dichlorobenzyl)-2-hydroxy-5-nitrobenzamide (IC50 = 2.0 μmol/L), 3,5-dibromo-N-(3,4-dichlorobenzyl)-2-hydroxybenzamide (IC50 = 2.3 μmol/L) and 3,5-dibromo-N-(4-chlorobenzyl)-2-hydroxybenzamide (IC50 = 2.6 μmol/L) with activity comparable with that of the standard Diuron (IC50 = 1.9 μmol/L). The PET inhibiting activity increased approximately linearly with increasing lipophilicity of the compounds as well as with the increasing sum of Hammett σ constants of the substituents on the acyl fragment (R1 = H, 5-OCH3, 5-CH3, 5-Cl, 5-Br, 5-NO2, 4-OCH3, 4-Cl, 3,5-Cl and 3,5-Br) and the benzylamide fragment (R2 = H, 4-OCH3, 4-CH3, 4-F, 4-Cl and 3,4-Cl). Based on the evaluated structure-PET inhibiting activity relationships (QSAR) it was confirmed that the inhibitory activity of the compounds depends on lipophilicity (log P or distributive parameters π 1 and ▂of individual substituents) and electronic properties of the substituents on the acyl (σ1) and the benzylamide fragments (σ2), the contribution of σ1 being more significant than that of σ2.

  研究了61种环取代的N-苄基水杨酰胺对菠菜叶绿体中光合电子传递(PET)的抑制作用。这些化合物的抑制能力以IC50值表示，范围从2.0到425.3 μmol/L。评估的化合物中有几种可被视为有效的PET抑制剂；其中包括N-(3,4-二氯苄基)-2-羟基-5-硝基苯甲酰胺(IC50 = 2.0 μmol/L)、3,5-二溴-N-(3,4-二氯苄基)-2-羟基苯甲酰胺(IC50 = 2.3 μmol/L)和3,5-二溴-N-(4-氯苄基)-2-羟基苯甲酰胺(IC50 = 2.6 μmol/L)，这些活性与标准敌草隆(IC50 = 1.9 μmol/L)相当。PET抑制活性随着化合物亲脂性的增加以及酰基片段(R1 = H, 5-OCH3, 5-CH3, 5-Cl, 5-Br, 5-NO2, 4-OCH3, 4-Cl, 3,5-Cl和3,5-Br)和苄胺片段(R2 = H, 4-OCH3, 4-CH3, 4-F, 4-Cl和3,4-Cl)上取代基的Hammett σ常数之和的增加而大致线性增加。基于评估的结构-PET抑制活性关系(QSAR)证实，这些化合物的抑制活性依赖于亲脂性(log P或分布参数π1和▂)以及酰基(σ1)和苄胺片段(σ2)上取代基的电子性质，其中σ1的贡献比σ2更为显著。
