报道了在C-9位含有氨基酸或二肽的新隐油菜籽衍生物的合成及其体外和体内抗肿瘤活性的评价。为了建立氨基酸或肽对5 H-吲哚并[2,3- b ]喹啉(DiMIQ)的理化性质的影响,研究了亲脂性和溶血性。与环磷酰胺相比,大多数化合物在体外均表现出高抗增殖活性,并在小鼠中强烈抑制肿瘤的生长。亲水性氨基酸或肽与疏水性DiMIQ的连接增加了其亲水性,并降低了其溶血活性。甘氨酰甘氨酸缀合物(7a)是最有前途的派生词。它强烈抑制了小鼠的肿瘤生长(剂量为50 mg kg –1天–1时,其在11–16天抑制了46–63%的肿瘤生长,在18–23天抑制了29–43%的肿瘤生长),并且显着与DiMIQ相比,可降低溶血活性并降低体内毒性。

in obtaining different compounds from those designed. Nevertheless, in all above cases we were able to obtain thiol-containing derivatives of selected biological active compounds. Moreover, a modelling study for the two-step thiolation of genistein and some of its derivatives was accomplished using the density functional theory (B3LP). A hypothesis on a possible reason for the unsuccessful deprotection

The synthesis of indolo[2,3-b]quinoline derivatives containing guanidine, amino acid or guanylamino acid substituents as well as their in vitro evaluation for the cytotoxic and antifungal activity are reported. The influence of the guanidine group on the selective cytotoxic and hemolytic properties of indolo[2,3-b]quinoline was investigated. Most of the compounds displayed a high cytotoxic activity
verifying the efficacy of common guanylation reagents in order to obtain the guanidine derivatives of indolo[2,3-b]quinoline has been performed. As a result, a high-yield procedure using N,N′-di-Boc-N′′-triflylguanidine was applied to synthesize the guanidine derivative of indolo[2,3-b]quinoline 1 in a gram scale for specific in vitro and in vivo biological research. Extensive studies on the antiproliferative
DNA–topoisomerase alpha and beta complexes. All of the conjugates studied showed approximately one order of magnitude strongerbinding to DNA compared to the reference DiMIQ, and approximately two orders of magnitude strongerbinding to the topoisomerase II–DNA complex compared to DiMIQ. Conjugate 2 was predicted to have the strongest binding to the enzyme–DNA complex, with a Ki value of 2.8 nM.
