Computational drug discovery for the Zika virus BJPS
Mottin,Melina; Borba,Joyce Villa Verde Bastos; Melo-Filho,Cleber Camilo; Neves,Bruno Junior; Muratov,Eugene; Torres,Pedro Henrique Monteiro; Braga,Rodolpho Campos; Perryman,Alexander; Ekins,Sean; Andrade,Carolina Horta.
Few Zika virus (ZIKV) outbreaks had been reported since its first detection in 1947, until the recent epidemics occurred in South America (2014/2015) and expeditiously became a global public health emergency. This arbovirus reached 0.5-1.3 million cases of ZIKV infection in Brazil in 2015 and rapidly spread in new geographic areas such as the Americas. Despite the mild symptoms of the Zika fever, the major concern is related to the related severe neurological disorders, especially microcephaly in newborns. Advances in ZIKV drug discovery have been made recently and constitute promising approaches to ZIKV treatment. In this review, we summarize current computational drug discovery efforts and their applicability to discovery of anti-ZIKV drugs. Lastly, we...

NS3 protease from flavivirus as a target for designing antiviral inhibitors against dengue virus Genet. Mol. Biol.
Natarajan,Satheesh.
The development of novel therapeutic agents is essential for combating the increasing number of cases of dengue fever in endemic countries and among a large number of travelers from non-endemic countries. The dengue virus has three structural proteins and seven non-structural (NS) proteins. NS3 is a multifunctional protein with an N-terminal protease domain (NS3pro) that is responsible for proteolytic processing of the viral polyprotein, and a C-terminal region that contains an RNA triphosphatase, RNA helicase and RNA-stimulated NTPase domain that are essential for RNA replication. The serine protease domain of NS3 plays a central role in the replicative cycle of dengue virus. This review discusses the recent structural and biological studies on the...

Recent Advances and Perspectives in Cancer Drug Design Anais da ABC (AABC)
MAGALHAES,LUMA G.; FERREIRA,LEONARDO L.G.; ANDRICOPULO,ADRIANO D..
ABSTRACT Cancer is one of the leading causes of death worldwide. With the increase in life expectancy, the number of cancer cases has reached unprecedented levels. In this scenario, the pharmaceutical industry has made significant investments in this therapeutic area. Despite these efforts, cancer drug research remains a remarkably challenging field, and therapeutic innovations have not yet achieved expected clinical results. However, the physiopathology of the disease is now better understood, and the discovery of novel molecular targets has refreshed the expectations of developing improved treatments. Several noteworthy advances have been made, among which the development of targeted therapies is the most significant. Monoclonal antibodies and...

Second-generation pterocarpanquinones: synthesis and antileishmanial activity J. Venom. Anim. Toxins incl. Trop. Dis.
Faiões,Viviane dos Santos; Frota,Lívia C. R. M. da; Cunha-Junior,Edézio Ferreira; Barcellos,Julio C. F.; Silva,Thayssa Da; Daher Netto,Chaquip; Da-Silva,Silvia Amaral Gonçalves; Silva,Alcides J. M. da; Costa,Paulo R. R.; Torres-Santos,Eduardo Caio.
Abstract Background: Despite the development of new therapies for leishmaniasis, among the 200 countries or territories reporting to the WHO, 87 were identified as endemic for Tegumentary Leishmaniasis and 75 as endemic for Visceral Leishmaniasis. The identification of antileishmanial drug candidates is essential to fill the drug discovery pipeline for leishmaniasis. In the hit molecule LQB-118 selected, the first generation of pterocarpanquinones was effective and safe against experimental visceral and cutaneous leishmaniasis via oral delivery. In this paper, we report the synthesis and antileishmanial activity of the second generation of pterocarpanoquinones. Methods: The second generation of pterocarpanquinones 2a-f was prepared through a...

THE CONTINUING VALUE OF NATURALPRODUCTS FOR DRUG DISCOVERY Rev Salud Anim.
Harvey,Alan L.
Natural products are the most consistently successful source of drug leads, both historically and currently. Despite this, the use of natural products in industrial drug discovery has fallen out of favour. Natural products are likely to continue to be sources of new commercially viable drug leads because the chemical novelty associated with natural products is higher than that of any other source: this is particularly important when searching for lead molecules against newly discovered targets for which there are no known small molecule leads. Despite the commonly held assumptions, natural products can be a more economical source of chemical diversity compared with synthesis of equivalent numbers of diverse chemicals. Additionally, natural products that...

The role of natural products in modern drug discovery. Anais da ABC (AABC)
CALIXTO,JOÃO B..
Abstract: The global medicine market is about 1.1 trillion US dollars. About 35 percent of medicines have originated from natural products. Brazil presents the largest biodiversity in the world, with more than 50,000 species of higher plants. However, few innovative products have been developed in Brazil from active constituents derived from the Brazilian biodiversity. Scientific evidences on plants and venoms have been internationally published by Brazilian scientists over the last 4 decades; but few examples of innovative products are commercially available. Few examples include the anti-hypertensive drug captopril first identified in the venom of the Brazilian viper Bothrops jararaca by Professor Sergio Ferreira; and some phytotherapeutic agents such as...
