Anopheles Gambiae Purine Nucleoside Phosphorylase: Catalysis, Structure And Inhibition, Erika Taylor, Agnes Rinaldo-Matthis, Lei Li, Mahmoud Ghanem, Keith Hazleton, M. Belen Cassera, Steven Almo, Vern Schramm
Erika A. Taylor, Ph.D.
The purine salvage pathway of Anopheles gambiae, a mosquito that transmits malaria, has been identified in genome searches on the basis of sequence homology with characterized enzymes. Purine nucleoside phosphorylase (PNP) is a target for the development of therapeutic agents in humans and purine auxotrophs, including malarial parasites. The PNP from Anopheles gambiae (AgPNP) was expressed in Escherichia coli and compared to the PNPs from Homo sapiens (HsPNP) and Plasmodium falciparum (PfPNP). AgPNP has kcat values of 54 and 41 s-1 for 2'-deoxyinosine and inosine, its preferred substrates, and 1.0 s-1 for guanosine. However, the chemical step is fast for …
Kehamilan Dan Kejadian Malaria Di Puskesmas Way Muli, Lampung Selatan, Ismen Ismen
Kehamilan Dan Kejadian Malaria Di Puskesmas Way Muli, Lampung Selatan, Ismen Ismen
Kesmas
Kelompok yang paling rentan terhadap malaria adalah wanita hamil dengan berbagai akibat terhadap ibu dan janin yang dikandungnya. Di Indonesia, penelit- ian tentang hubungan kehamilan dengan kejadian malaria masih sangat jarang dilakukan. Tujuan penelitian ini adalah mengetahui hubungan antara kehamilan dengan kejadian malaria. Penelitian ini menggunakan desain studi kasus control dengan sumber data proner di populasi di wilayah kerja Puskesmas Way Muli Kecamatan Rajabasa, Kabupaten Lampung Selatan, Provinsi Lampung. Populasi studi adalah wanita usia 15 – 49 tahun yang datang pada saat penelit- ian pada periode November sampai dengan Desember 2006. Pengumpulan data dengan cara wawancara dan pengambilan sediaan darah. …

Plasmodium falciparum is one of four species known to cause malaria in humans and is the species that is associated with the most virulent form of the disease. Malaria causes nearly two million deaths each year, many of these occurring among children in under-developed countries of the world. One reason for this is the prevalence of drug resistant strains of malaria that mitigate the efficacy of existing drugs. Hence, the identification of a new generation of pharmacological agents for malaria is extremely urgent. The recent identification of a group of novel protein kinases within the Plasmodium falciparum genome has provided …

A series of novel 10-N-substituted acridones, bearing alkyl side chains with tertiary amine groups at the terminal position, were designed, synthesized, and evaluated for the ability to enhance the potency of quinoline drugs against multidrug-resistant (MDR) Plasmodium falciparum malaria parasites. A number of acridone derivatives, with side chains bridged three or more carbon atoms apart between the ring nitrogen and terminal nitrogen, demonstrated chloroquine (CQ)-chemosensitizing activity against the MDR strain of P. falciparum (Dd2). Isobolograrn analysis revealed that selected candidates demonstrated significant synergy with CQ in the CQ-resistant (CQR) parasite Dd2 but only additive (or indifferent) interaction in the CQ-sensitive …
