Synthesis and Structure-Activity Relationships of Tambjamines and B-Ring Functionalized Prodiginines as Potent Antimalarials

Synthesis and antimalarial activity of 94 novel bipyrrole tambjamines (TAs) and a library of B-ring functionalized tripyrrole prodiginines (PGs) against a panel of Plasmodium falciparum strains are described. The activity and structure-activity relationships demonstrate that the ring-C of PGs can be replaced by an alkylamine, providing for TAs with retained/enhanced potency. Furthermore, ring-B of PGs/TAs can be substituted with short alkyl substitutions at either 4-position (replacement of OMe) or 3- and 4-positions without impacting potency. Eight representative TAs and two PGs have been evaluated for antimalarial activity against multidrug-resistant P. yoelii in mice in the dose range of 5-100 mg/kg ¡Á 4 days by oral administration. The KAR425 TA offered greater efficacy than previously observed for any PG, providing 100% protection to malaria-infected mice until day 28 at doses of 25 and 50 mg/kg ¡Á 4 days, and was also curative in this model in a single oral dose (80 mg/kg). This study presents the first account of antimalarial activity in tambjamines.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 50541-93-0, and how the biochemistry of the body works.50541-93-0

The atmosphere was changed to carbon monoxide. The reaction was conducted for the given reaction time upon stirring at 50 C and analyzed by Gc and GC-MS. The cooled reaction mixture was then distilled to dryness under reduced pressure. The residue was dissolved in chloroform (15 mL) and washed twice with water (15 mL). The organic phase was dried over Na2SO4, filtered and evaporated under reduced pressure to a solid material. All compounds (except 10a, 10b) were subjected to column chromatography (Silicagel 60 (Sigma), 0.063-0.200 mm) or Aluminum oxide (Sigma), activated, neutral, Brockmann activity I), CHCl3/MeOH or CHCl3/EtOH eluent mixtures (the exact ratios are specified in Characterization (3.4) for each compound).
