AI Article Synopsis

  • * The research focuses on inhibiting deoxyhypusine hydroxylase, an enzyme in the polyamine pathway, to discover new therapies for these diseases.
  • * Two compounds, 3,5-diethyl piperidone derivatives and piperidine oximether 53, showed promising activity against Trypanosoma brucei brucei, Plasmodium falciparum, and even inhibited HIV-1 replication with low toxicity to human cells.

Article Abstract

Malaria, sleeping sickness, Chagas' disease, Aleppo boil, and AIDS are among the tropical diseases causing millions of infections and cases of deaths per year because only inefficient chemotherapy is available. Since the targeting of the enzymes of the polyamine pathway may provide novel therapy options, we aimed to inhibit the deoxyhypusine hydroxylase, which is an important step in the biosynthesis of the eukaryotic initiation factor 5A. In order to identify new lead compounds, piperidines were produced and biologically evaluated. The 3,5-diethyl piperidone-3,5-dicarboxylates 11 and 13 substituted with 4-nitrophenyl rings in the 2 and 6 positions were found to be active against Trypanosoma brucei brucei and Plasmodium falciparum combined with low cytotoxicity against macrophages. The corresponding monocarboxylates are only highly active against the T. brucei brucei. The piperidine oximether 53 demonstrated the highest plasmodicidal activity. Moreover, compounds 11 and 53 were also able to inhibit replication of HIV-1.

Unlabelled: Respiratory and encephalitic virus infections represent a significant risk to public health globally. Detailed investigations of immunological responses and disease outcomes during sequential virus infections are rare. Here, we define the impact of influenza virus infection on a subsequent virus encephalitis.

Circulating sexual stages of ) can be transmitted from humans to mosquitoes, thereby furthering the spread of malaria in the population. It is well established that antibodies can efficiently block parasite transmission. In search for naturally acquired antibodies targets on sexual stages, we established an efficient method for target-agnostic single B cell activation followed by high-throughput selection of human monoclonal antibodies (mAbs) reactive to sexual stages of in the form of gametes and gametocyte extracts.

Previous studies in sports science suggested that regular exercise has a positive impact on human health. However, the effects of endurance sports and their underlying mechanisms are still not completely understood. One of the main debates regards the modulation of immune dynamics in high-intensity exercise.

Background: Polyamines have been suggested to play pivotal roles in ischemic stroke and neurodegenerative disorders, but the associations of plasma polyamines with poststroke cognitive impairment (PSCI) remain unclear. We aimed to prospectively investigate the associations of plasma putrescine, spermidine, and spermine with PSCI among patients with ischemic stroke in a multicenter cohort study.

Methods And Results: We measured plasma polyamine levels at baseline among 619 patients with ischemic stroke from a preplanned ancillary study of CATIS (China Antihypertensive Trial in Acute Ischemic Stroke).

Background: Snakebite is a priority neglected tropical disease, but incidence data are lacking; current estimates rely upon incomplete health facility reports or ad hoc surveys. Spatial analysis methods harness statistical associations between case incidence and spatially varying factors to improve estimates. This systematic review aimed to identify variables associated with snakebite risk in spatial and temporal analyses for inclusion in geospatial studies to improve risk estimation accuracy.
