  Preparation and antitrypanosomal activity of secochiliolide acid derivatives

  摘要：

  Secochiliolide acid (1) isolated from the Patagonian shrub Nardophyllum biyoides, was used as a scaffold for the preparation of a series of nine derivatives. Compound 1 and its derivatives were tested against Trypanosoma cruzi epimastigotes grown in liquid media. It was first observed that secochiliolide acid (1) inhibited the proliferation of the parasites, with an IC50 of 2 mu g/mL. Six of the synthesized derivatives were also active with IC50's between 2 and 7 mu g/mL which are comparable to that of the commercial drug benznidazole (2.5 mu g/mL). These results indicate that the carboxyl group is not essential for the bioactivity of 1, while the presence of the tetrasubstituted exocyclic double bond seems to be important. Moreover, the presence of the furan and spirolactone rings is not essential for the bioactivity per se, but is important in combination with other structural fragments present in the molecule.

The aerial parts of gave two of the new diterpenes and three further diterpenes which are closely related to those of the species. Further-more two new geranyl geraniol derivatives were present. The

  AbstractIn the present study, a series of new esters of secochiliolide acid (SA), a diterpene isolated from Nardophyllum bryoides, were synthesized in good yield. All compounds were evaluated for their in vitro antiparasitic properties (on Plasmodium falciparum and Trypanosoma brucei brucei) and cytotoxicity (on WI38, normal mammalian cells). They displayed moderate antitrypanosomal activity with IC50 values between 2.55 and 18.14 μm, with selectivity indices >10, and low antiplasmodial effects with IC50 > 29 μm. The only exception was the n‐hexyl ester of SA, which showed a strong and selective antiplasmodial activity (IC50 = 1.99 μm and selectivity index = 117.0). The in vivo antimalarial efficacy of this compound was then assessed according to the 4‐day suppressive test of Peters in mice. An intraperitoneal treatment at 50 mg kg−1 day−1 induced a slight parasitaemia reduction by 56% which was statistically significant on day 4 post‐infection and an increase in the survival time.
