Synthesis and in Vitro and in Vivo Antimalarial Activity of New 4-Anilinoquinolines
摘要:
A new series of 4-anilinoquinolines with two proton-accepting side chains has been synthesized. Antimalarial activity and levels of cytotoxicity upon both MRC-5 cells and macrophages were found to be highly dependent upon the features of these side chains. Several compounds were found to be active in the low nanomolar range, against both chloroquine-sensitive and -resistant strains of Plasmodium falciparum in vitro. From among them, a morpholino derivative cured mice infected by Plasmodium berghei and displayed a lower toxicity than amodiaquine upon mouse macrophages.

in culture. Among 9-(3',5'-disubstituted anilino)acridines, 3-(9-acridinylamino)-5-(hydroxymethyl)aniline (AHMA) was found to be a potent topoisomerase II inhibitor and exhibited significant antitumor efficacy both in vitro and in vivo. Chemotherapy of solid-tumor-bearing mice with 10, 10, and 5 mg/kg (QD x 4, ip) AHMA, VP-16, and m-AMSA, respectively, resulted in more tumor volume reduction by AHMA
合成了一系列插入DNA的9-苯胺基cr啶,即9-苯氧基ac啶,9-(苯硫基)ac啶和9-(3',5'-二取代的苯胺基)ac啶,它们可能对DNA拓扑异构酶II具有抑制作用。与氨水扁桃碱(m-AMSA)不同,这些试剂旨在避免氧化代谢途径。因此,预期这些a啶衍生物在血浆中具有长的半衰期。发现9-苯氧基ac啶和9-(苯硫基)ac啶对培养的小鼠白血病L1210和人类白血病HL-60细胞均具有中等细胞毒性。在9-(3',5'-二取代的苯胺基)ac啶中,发现3-(9-ac啶基氨基)-5-(羟甲基)苯胺(AHMA)是有效的拓扑异构酶II抑制剂,在体外和体外均表现出显着的抗肿瘤功效体内。分别以10、10和5 mg / kg(QD x 4,ip)AHMA,VP-16和m-AMSA化疗的实体瘤小鼠,与VP-相比,AHMA减少的肿瘤体积更大16或m-AMSA用于E0771乳腺腺癌和B-16黑色素瘤。对于刘易斯肺癌

Protein kinase C (PKC) is a widely studied molecular target for the treatment of cancer and other diseases. We have approached the issue of modifying PKC function by targeting the C1 domain in the regulatory region of the enzyme. Using the X-ray crystal structure of the PKC δ C1b domain, we have discovered conveniently synthesizable derivatives of dialkyl 5-(hydroxymethyl)isophthalate that can act
double protonation of the cyclam ring takes place before protonation of the dansyl units; 2) the oligoethyleneglycolchains do not interfere with protonation of the cyclamcore and the dansyl units in the ground state, but affect the luminescence of the protonated dansyl units; 3) the first equivalent of metal ion is coordinated by the cyclamcore; 4) the interaction of the resulting cyclam complex
naphthalene localized and naphthalene excimer emission similar to those observed in the case of N8, together with a much stronger dansyl emission with maximum at 525 nm. Addition of CF3SO3H to dendrimer solutions in CH3CN/CH2Cl2 1:1 (v/v) leads to protonation of the aliphatic amine units of the cyclam core at first and then of the aromatic amine of each dansyl chromophores. Cyclam can be diprotonated
