Six compounds, all newly synthesized triazole-pyrimidine derivatives that proved inhibitory of in in vitro growth of epimastigotes in Trypanosoma cruzi and of promastigotes of Leishmania donovani and Phytomonas staheli, were studied to investigate their toxic effects. As a biological model, the plant trypanosome P. staheli, which causes sudden wilt in the oil palm and Hartrot in the coconut pal...

Organic compounds are synthesized in the interstellar medium and can be delivered to planetary surfaces such as the early Earth, where they mix with endogenous species. Some of these compounds are amphiphilic, having polar and nonpolar groups on the same molecule. Amphiphilic compounds spontaneously self-assemble into more complex structures such as bimolecular layers, which in turn form closed...

In the present work, the knowledge on target proteins of standard antibiotics was extended to antimicrobial mushroom compounds. Docking studies were performed for 34 compounds in order to evaluate their affinity to bacterial proteins that are known targets for some antibiotics with different mechanism of action: inhibitors of cell wall synthesis, inhibitors of protein synthesis, inhibitors of n...

  Background & Objectives: Antisense peptide nucleic acids (PNA) that target growth essential genes show potent bactericidal properties without cell lysis. We considered the possibility that whether PNA treatment influence the bacteria total nucleic acids content and apply approach to develop a new delivery system to Dendritic cells (DCs). DCs are the most potent antigen presenting cells in th...

background nucleic acid based detection of mycobacterium tuberculosis has the potential to improve the analysis of the tuberculosis epidemiology and patient care by increasing the specificity and sensitivity of diagnosis. patients and methods fifty suspected cases were screened for m. tuberculosis by using a new primer sequence and comparing its results with the primer (is6110) most widely used...

Despite extensive efforts to repurpose approved drugs, discover new small molecules, and develop vaccines, COVID-19 pandemic is still claiming victims around the world. The current arsenal of antiviral compounds did not perform well in past viral infections (e.g., SARS), which casts a shadow doubt for use against SARS-CoV-2. Vaccines should offer ultimate protection; however, there limited info...

Nucleic acids have been considered interesting molecules to be used as biopharmaceuticals for the treatment of various diseases, in gene therapy strategies. In particular, RNA arises most promising approach because it does not require access nucleus cells exert its function; however, is quite challenging due labile nature. To increase possibility translating RNA-based technology clinical protoc...
