Inhibitory effects of nine carbocyclic DNA minor groove binders on amidolytic activities of plasmin, trypsin and urokinase were examined. Some of the studied compounds affected plasmin or trypsin activity, but not urokinase activity. One of the pentamidine analogues (5) and two bis-netropsin like compounds (6, 8) were potent inhibitors of plasmin (IC50 equals 90 and 100 microM), whereas an anal...
Clinical and pathological findings are described in two AIDS patients with Pneumocystis carinii infection who received prophylactic treatment with nebulised pentamidine and developed unusual hepatic and renal failure. Histological examination showed clumps of P carinii massively obstructing hepatic sinuses and portal vessels in the first patient, and merular and intertubular capillaries in the ...
Pentamidine (PEN) is a second-line agent in the treatment of leishmaniasis whose mode of action and resistance is not well understood. Here, we used a genetic strategy to search for loci able to mediate PEN resistance (PENr) when overexpressed in Leishmania major. A shuttle cosmid library containing genomic DNA inserts was transfected into wild-type promastigotes and screened for PEN-resistant ...
Human African trypanosomiasis is a devastating disease with only a few treatment options, including pentamidine. Diamidine compounds such as pentamidine, DB75, and DB820 are potent antitrypanosomal compounds. Previous investigations have shown that diamidines accumulate to high concentrations in trypanosomes. However, the mechanism of action of this class of compounds remains unknown. A long-hy...
Trimethoprim-sulfamethoxazole and pentamidine isethionate have been used extensively for the prophylaxis and therapy of pneumonia caused by Pneumocystis jirovecii. Problems associated with toxicity and potential emerging resistance for both therapies necessitate the development of safe and effective analogs or new treatment strategies. In the present study, a library of 36 compounds was synthes...
The dodecanucleotide d(CGCGATATCGCG)2 was characterized by thermodynamic and UV-spectrophotometric measurements. A van't Hoff enthalpy of delta H(uv)v.H. approximately -190 kJ/mol was determined for the thermal transition using UV spectroscopy. This value was confirmed by differential scanning calorimetry (DSC). In addition we obtained the thermodynamic data delta HDSC = -405.1 kJ/mol, delta SD...
