4-Hydroxy-5-phenylpyrido[3,2,1-jk]carbazol-6-ones (4, 5), which were obtained from carbazoles 1 and malonates 2 or 3, were converted to reactive intermediates such as 4-chlorides 9 or 4-tosylates 10, which gave in turn 4-azido-5-phenyl derivatives 11. 5-Alkyl-4-azides 11 were not obtained in this manner; however a new one-pot azidation reaction was developed starting from 4-hydroxy derivatives 4 which

Amination of 4-hydroxypyridocarbazolones 1 with aniline or benzylamine gave in good yields 4-amines 3. With piperidine in a sealed tube from 4-hydroxy- or 4-chloro-5-alkylpyridocarbazolones 1 or 4 ring opened 1-acylcarbazoles 5 were obtained. Only 4-hydroxy-5-phenyl-pyridocarbazolone 1d gave 4-amines 6. Reduction of 4-azidopyridocarbazolones 7 either by catalytic hydrogenation or in a 2-step synthesis
用苯胺或苄胺将4-羟基吡啶并咔唑酮1胺化,得到4-胺3的产率很高。用哌啶在密封管中从4-羟基-或4-氯-5-烷基吡啶并咔唑酮1或4开环得到1-酰基咔唑5。仅4-羟基-5-苯基-吡啶并咔唑酮1d给出4-胺6。通过催化氢化或在两步合成中通过磷腈8还原4-叠氮吡啶并咔唑酮7得到4-氨基吡啶并咔唑酮9。胺9也可从苄胺3中获得通过催化脱苄基作用。4-羟基-5- phenylpyridocarbazolone的一个步骤胺化1D 通过脱苄基化至9d中是通过用苄基氯化铵反应观察到。在升高的温度下,从1d开始形成高度熔融的6,13b-二氮杂茚并[1,2,3- hi ] chrysenone 10。

A novel Hemozoin Detoxification Protein (HDP) from
Plasmodium
and related parasites is provided as a target for therapeutic intervention in diseases caused by the parasites. HDP has been shown to play a critical role in adhesion to, or invasion into, host cells by the parasite. Furthermore, HDP catalyzes the neutralization of heme by the parasite, by promoting its polymerization into hemozoin. This invention provides methods and compositions for therapies based on the administration of protein, DNA or cell-based vaccines and/or antibodies based on HDP, or antigenic epitopes of HDP, either alone or in combination with other parasite antigens. Methods for the development and use of compounds that inhibit the catalytic activity of HDP, and diagnostic and laboratory methods utilizing HDP are also provided. HDP is also referred to herein as Fasciclin Related Adhesive Protein (FRAP).

[FR] L'invention concerne une nouvelle protéine de désintoxication de l'hémozoïne (PDH) de plasmodium et de parasites apparentés, comme cible pour intervention thérapeutique dans des maladies causées par lesdits parasites. La PDH s'est avéré jouer un rôle critique dans l'adhésion à des, ou l'invasion de, cellules hôtes par le parasite. En outre, La PDH catalyse la neutralisation de l'hème par le parasite, en encourageant sa polymérisation en hémozoïne. La présente invention concerne des méthodes et des compositions pour des thérapies basées sur l'administration de vaccins à base de protéine, d'ADN ou de cellules, et/ou d'anticorps basés sur la PDH ou d'épitopes antigènes de la PDH, seuls ou en combinaison avec d'autres antigènes de parasites. L'invention concerne aussi des méthodes pour développer et utiliser des composés qui inhibent l'activité catalytique de la PDH, et des méthodes diagnostiques et de laboratoire utilisant la PDH. On fait également référence ici à la PDH comme protéine adhésive apparentée à la fascicline (FRAP : Fasciclin Related Adhesive Protein).
