中文摘要
Riscoe博士的实验和化疗实验室专注于药物的发现、治疗的优化和治疗的翻译。
抗寄生虫药物的开发,特别是治疗疟疾和预防疟疾的药物的开发,面临着严峻的挑战和挑战。
一种可能致命的热带疾病。在他的实验室里,他正在使用药物设计和化学合成的现代技术方法。
已经成功地创造了5种新颖的抗疟疾药物“化学类型”,在它们所属的每一种药物类别中都有几个具有示范性的分子。
在感染的小鼠模型中,口服生物利用型药物和治疗药物。美国波特兰退伍军人管理局和邻近的俄亥俄州立大学已经提交了申请。
对于所有5种主要化学类型的专利保护,将包括:(1)具有良好血液和临床活性的双功能吡喃酮类药物。
它可以与许多标准的抗疟疾药物、4-氨基喹啉和衍生物协同作用。
(Pharmachins),旨在取代氯喹的药物,表示他们正在迅速有效地对抗这些耐多药药物的新菌株。
疟原虫、恶性疟原虫和寄生虫,(3)喹诺酮类(即EELQ-300)可以阻止寄生虫和线粒体的呼吸。
并对寄生虫发育的血液、肝脏、配子体、母体和媒介进行治疗,(4)使用ELQ-300的前药。
改进了可注射缓释药物的口服给药方法和方法,以及预防疟疾、疟疾和疟疾的长期药物保护措施。
Biguanide与其他抗呼吸道和抗疟疾药物(如他托瓦酮)联合使用,具有增强的协同作用。
和EELQ--300。
值得注意的是,ELQ基因(如EELQ-316)对包括弓形虫在内的其他寄生虫也有很强的抵抗力。
弓形虫和微小巴贝斯虫在体外和体内都表现出良好的生物活性,是一种真正的真核生物。
据估计,细胞内寄生虫已经感染了全球数十亿人,使他们面临长期的风险。
弓形虫病。包括胎儿和免疫受损的人(例如,艾滋病毒患者、移植患者和患者)。
正在接受癌症(化疗)的个人很容易患上严重的弓形虫病,这种疾病可能是致命的。
导致永久性视力障碍或神经功能障碍。即使是身体健康但没有免疫缺陷的人也很容易受到影响。
一种可能导致视力丧失的眼科疾病。他引起巴贝斯虫病,这种病通常是通过扁虱传播的。但这是不可能的。
在美国北部新英格兰地区流行的疾病被称为“楠塔基特热病”,就像疟疾一样。
弓形虫病,又称巴贝斯虫病,是一种具有潜在致命性的传染病,迫切需要一种新的治疗方法和有效的治疗药物。
值得注意的是,B.Microti是一种与莱姆氏病相关的常见混合感染疾病,被认为是该病的主要原因。
最重要的是,传染性疾病的风险增加了美国最大的血液供应。
美国波特兰退伍军人管理局的实验和化疗实验室还研究了药物作用的机制,包括使用药物。
这些方法是传统的方法,可以覆盖生物化学、化学和生物学以及分子和寄生虫学这三个领域。
Riscoe的实验室得到了美国退伍军人事务部、美国国立卫生与公众服务部、美国国家卫生与公众服务部的支持。
他所在的世界疟疾药物公司和他所在的公司与美国疾病控制和预防司的其他成员保持着积极的合作关系。
实验药物治疗学在沃尔特·里德陆军医学研究所工作。他继续担任受邀专家。
审查员为美国国防部的国家同行审查了美国医学研究发展计划(PRMRP)计划,并审查了美国国立卫生研究院(NIH)。
Riscoe博士的全球疟疾研究小组的目标是致力于开发既便宜、又安全、又有效的药物。
为最脆弱的儿童、幼儿和孕妇、妇女和儿童提供预防和治疗服务
最终需要开发一种新的鸡尾酒药物,这种药物可能不会被用来进一步根除这种疾病。
英文摘要
Dr. Riscoe’s Experimental Chemotherapy laboratory focuses on the discovery, optimization and translational
development of antiparasitic drugs, especially drugs for treatment and prevention of malaria, a severe and
potentially fatal tropical disease. Using modern methods of drug design and chemical synthesis his laboratory
has successfully created 5 novel antimalarial “chemotypes” with exemplary molecules in each category that are
orally bioavailable and curative in mouse models of infection. The Portland VA and neighboring OHSU have filed
for patent protection on all 5 chemotypes which include: 1) Dual functional acridones with blood stage activity
that interact synergistically with many standard antimalarial agents, 2) 4-Aminoquinoline derivatives
(“Pharmachins”), designed to replace chloroquine, that are rapidly active against multidrug resistant strains of
Plasmodium falciparum parasites, 3) Quinolones (i.e., ELQ-300) that block parasite mitochondrial respiration
and act vs. the blood, liver, gametocyte, and vector stages of parasite development, 4) Prodrugs of ELQ-300 for
improved oral delivery and for injectable sustained-release and long-term protection against malaria, and 5)
Biguanides with enhanced synergy in combination with anti-respiratory antimalarial drugs such as atovaquone
and ELQ-300.
It is noteworthy that ELQs (e.g., ELQ-316) are also potent against other parasites including Toxoplasma
gondii and Babesia microti with proven activity demonstrated in vitro as well as in vivo. T. gondii is a eukaryotic
intracellular parasite estimated to have infected billions of people worldwide, placing them at risk for
toxoplasmosis. Fetuses and immune-compromised persons (e.g., HIV patients, transplant patients, and
individuals undergoing cancer chemotherapy) are susceptible to severe toxoplasmosis, which can be fatal or
lead to permanent ocular or neurologic disability. Even healthy people without immunodeficiency are susceptible
to ocular disease which may cause vision loss. B. microti causes babesiosis which is transmitted by ticks. It is
endemic in the New England region of the United States where it is called, “Nantucket Fever”. Like malaria and
toxoplasmosis, babesiosis is a potentially fatal infection and new and effective drugs are urgently needed. It is
noteworthy that B. microti is a common co-infection associated with Lyme disease and is regarded as the
foremost infectious risk to the U.S. blood supply.
The Portland VA’s Experimental Chemotherapy Lab also investigates drug mechanism of action by use of
methods that are traditional to the fields of biochemistry, chemical biology and molecular parasitology. Dr.
Riscoe’s laboratory receives support from the Department of Veterans Affairs, National Institutes of Health, and
the Medicines for Malaria Venture and he maintains an active collaboration with members of the Division of
Experimental Therapeutics at the Walter Reed Army Institute for Research. He continues to serve as an invited
reviewer for the US DOD’s Peer Reviewed Medical Research Program (PRMRP) and the NIH. The long-term
objective of Dr. Riscoe’s malaria research is to develop drugs that are inexpensive, safe and effective in
prevention and treatment of the most vulnerable populations, young children and pregnant women, and
ultimately to develop a cocktail of drugs that may be used to eradicate the disease.
