Background: Many of present chemotherapeutics are inadequate and also resistant against visceral leishmaniasis (VL), an immunosuppressive ailment caused by . Despite the interest in plant-based drug development, no antileishmanial drugs from plant source are currently available. had been reported in favor of being immune modulators along with other traditional uses. Novel anti-VL therapies can rely on host immune-modulation with associated leishmanicidal action.
Objective: Discovery of novel plant-based antileishmanial compound from having permissible side effects.
Methods: With this rationale, an n-BuOH fraction of the methanolic extract of were evaluated against acellular and intracellular . Immunostimulatory activity of them was confirmed by elevated TNF-α and extracellular NO production from treated MФs and was found nontoxic to the host cells. Identification and structure confirmation for isolated Spergulin-A was performed by ESI-MS,C, and H NMR.
Results: Spergulin-A was found ineffective against the acellular forms while, against the intracellular parasites at 30 μg/mL, the reduction was 92.6% after 72 hrs. Spergulin-A enhanced ROS and nitric oxide (NO) release and changes in Gp91-phox, i-NOS, and pro and anti-inflammatory cytokines elaborated its intracellular anti-leishmanial activity.
Conclusion: The results supported that can potentiate new lead molecules for the development of alternative drugs against VL.

Unlabelled: Visceral leishmaniasis (VL), caused by , remains challenging to treat due to severe side effects and increasing drug resistance associated with current chemotherapies. Our study investigates the anti-leishmanial potential of from Uttarakhand, India, with extracts prepared from leaves and stems using ethanol and hexane. Advanced GC-MS analysis identified over 100 bioactive compounds, which were screened using molecular docking to assess their binding to LdHEL-67, a DDX3-DEAD box RNA helicase of donovani.

Problem: Leishmaniasis is a disease caused by protozoan parasites of the genus and has a high prevalence and impact on global health. Currently, the available drugs for its treatment have drawbacks, such as high toxicity, resistance of the parasite, and high cost. Therefore, the search for new, more effective, and safe drugs is a priority.

Background And Purpose: Leishmaniasis is a globally prevalent vector-borne disease caused by parasites of the genus Leishmania. The available chemotherapeutic drugs present problems related to efficacy, emergence of parasite resistance, toxicity and high cost, justifying the search for new drugs. Several classes of compounds have demonstrated activity against Leishmania, including icetexane-type diterpenes, previously isolated from Salvia and other Lamiaceae genera.

Cutaneous leishmaniasis (CL) is a zoonotic disease, manifested as chronic ulcers, potentially leaving unattractive scars. There is no preventive vaccination or optimal medication against leishmaniasis. Chemotherapy generally depends upon a small group of compounds, each with its own efficacy, toxicity, and rate of drug resistance.
