Compared Antileishmanial Activity of Clomiphene and Tamoxifen.

Drug repositioning is an efficient strategy to search for new treatment alternatives that is especially valuable for neglected parasitic diseases such as leishmaniasis. Tamoxifen and raloxifene are selective estrogen receptor modulators (SERMs) that have shown antileishmanial activity. Clomiphene is a SERM structurally similar to tamoxifen, whose antileishmanial potential is unknown.

3-Alkoxy-1-Benzyl-5-Nitroindazole Derivatives Are Potent Antileishmanial Compounds.

Indazoles have previously been identified as molecules with antiprotozoal activity. In this study, we evaluate the in vitro activity of thirteen 3-alkoxy-1-benzyl-5-nitroindazole derivatives (series D) against , and . In vitro, cytotoxicity against mouse peritoneal macrophages and growth inhibitory activity in promastigotes were evaluated for all compounds, and those showing adequate activity and selectivity were tested against intracellular amastigotes.

Detergent-free parasite transformation and replication assay for drug screening against intracellular Leishmania amastigotes.

Leishmaniasis is an infectious disease caused by protozoan species in the genera Leishmania and Endotrypanum. Current antileishmanial drugs are limited due to adverse effects, variable efficacy, the development of resistant parasites, high cost, parenteral administration and lack of availability in endemic areas. Therefore, active searching for new antileishmanial drugs has been done for years, mainly by academia.

[Ovarian pregnancy. Case report and review of the subject].

A case of a 21-year-old single woman with an acute abdomen, vaginal bleeding and an anemic syndrome is presented. Physical examination and ultrasonography showed an enlarged uterus and a little mass in the right ovary, which was thought to be a fibroma versus pregnancy. Serum levels of chorionic gonadotropin were increased.
