    • 6 cells/mL. Cell growth was followed by measuring everyday the absorbance of the culture at 600 nm. Before inoculation, the media was supplemented with the indicated amount of the drug from a stock solution in DMSO. The final concentration of DMSO in the culture media never exceeded 0.4% and the control was run in the presence of 0.4% DMSO and in the absence of any drug. No effect on epimastigotes growth was observed by the presence of up to 1% DMSO in the culture media. Growth of the parasite was followed for 11 days by measuring the increase in absorbance at 600 nm, which was proved to be proportional to the number of cells present.

    • 20 Compounds were constructed and studied as 7-substituted derivatives. The energy of each compound was minimised by molecular mechanics methods (using SYBYL molecular mechanics force fields implemented in PC SPARTAN Pro package) and then by semiempirical methods (AM1). With the structure of minimum energy a single point calculation were performed using AM1 semiempirical method implemented in the package. LogP calculated (CLogP) by Villar algorithm implemented in PC SPARTAN Pro package was used
