amination of 2-chlorobenzoic acids with aniline derivatives has been developed. The method eliminates the need for acid protection and produces a wide range of N-aryl anthranilic acid derivatives in up to 99% yield. The amination was found to proceed with both electron-rich and electron-deficient aryl chlorides and anilines and also utilizes sterically hindered anilines such as 2,6-dimethylaniline and
(STE20/SPS1-related proline/alanine-rich kinase) and NCC (NaCl cotransporter) results in characteristic salt-sensitive hypertension. Thus, inhibitors of the WNK-OSR1/SPAK-NCC cascade are candidates for a new class of antihypertensive drugs. In this study, we developed novel inhibitors of this signal cascade from the 9-aminoacridine lead compound 1, one of the hit compounds obtained by screening our chemical library for

work was to establish quantitative relationships between the biological activity of thiosemicarbazides of substituted phenylanthranyl acids and their physicochemical parameters. For that purpose, we have synthesized 18 thiosemicarbazides ( I -XVII I ) using the reaction of acylation [3] of thiosemicarbazide by chloroanhydrides of the corresponding phenylanthranyl acids [4]. The resulting thiosemicarbazides
苯蒽酸衍生物作为抗炎、镇痛、解热药物广泛应用于实用医学,并作为寻找新的有效药物制剂的起始物质[1, 2]。然而,文献中没有报道对这些化合物的生物活性与其理化性质之间的关系进行系统研究。这项工作的目的是建立取代苯蒽基酸缩氨基硫脲的生物活性与其理化参数之间的定量关系。为此,我们使用相应苯蒽基酸的氯酸酐酰化氨基硫脲 [3] 的反应合成了 18 种氨基硫脲 (I -XVII I)。所得氨基硫脲I-XVII I表现为结晶物质,可溶于二恶烷、乙醇、苯和DMF,不溶于水。合成的化合物 I XVIII 的建议结构通过 IR 和 UV 光谱数据确认,并通过 TLC 在适当的溶剂系统中检查其纯度(表 I)。化合物 I XVIII 的 IR 光谱在 1587 1573 cmi(NH 基团的弯曲振动,酰胺 II)、16531620 cm -I(拉伸振动,酰胺 I)和 1253 1220 cml(C 的振动)区域包含吸收带=S

Synthesis of several new 9‐anilino, phenylhydrazino, and sulphonamidoanalogs of 2‐ or 4‐methoxy‐6‐nitroacridine derivatives is described. The prepared compounds were tested for their in vitro antitumoractivity against 60 human tumor cell lines by the National Cancer Institute (NCI) and showed a potential anticancer activity. Compounds 9‐(phenylhydrazino)‐2‐methoxy‐6‐nitroacridine (8a) and 9‐(4‐c
