In-Silico Selection of Wound-Healing Plant Secondary Molecules and Their Pro-Healing Activities on Experimental Models.

This study explored the potential of plant-derived molecules (PDMs) as a medicinal treatment for skin wounds. To assess their healing properties, 34 potential drug molecules (PDMs) and ten therapeutic targets were subjected to molecular docking and dynamics analysis, with allantoin used as a standard compound. Although aristolochic acid had the most potent inhibitory effect, its toxicity made it unsuitable for testing on cells and mice. Therefore, ß-caryophyllene (BC) and caryophyllene oxide (BCoxide) were chosen for further testing. The results showed that BC-treated HaCat cells had significantly improved scratch area closure, and both BC and BCoxide treatment produced positive effects such as reduced dermal cellularity and mast cells, decreased levels of inflammation markers IL-6 and TNF-α, and an increase in collagen deposition in mice tissues. However, these treatments did not accelerate wound healing. This study suggests that the PDMs selected based on in-silico results have significant potential for pro-healing abilities. It is essential to conduct further research to confirm our findings.

[Evaluation of ketoconazole formulations for topical use in cutaneous leishmaniasis caused by Leishmania (Viannia)]. / Evaluación de formulaciones de ketoconazol para uso tópico en leishmaniasis cutánea por Leishmania(Viannia).

The effectiveness of various pharmaceutical formulations of ketoconazole was evaluated in experimental models of cutaneous leishmaniasis (LC) in BALB C mice. Topical gel, lipogel, and cream formulations containing permeation enhancers and different concentrations of ketoconazole were prepared. Stability, toxicity and anti-Leishmania activity were determined in vitro. In addition, the effectiveness of topically applied formulations in LC-infected mice infected with Leishmania (Viannia) braziliensis was evaluated in vivo. Cream formulations were additionally evaluated in mice infected with L. (V.) panamensis. The systems evaluated maintained in vitro the activity of ketoconazole against parasites; however, none of the formulations were effective in curing LC lesions in mice. Topical treatment with miltefosine (used as a control) cured the lesions. It is concluded that the ketoconazole-containing formulations designed in this study were not effective against LC in infected mice.

Se evaluó la efectividad de diversas formulaciones farmacéuticas de ketoconazol en modelos experimentales de leishmaniasis cutánea (LC) en ratones BALB C. Fueron preparadas formulaciones tópicas tipo gel, lipogel y crema conteniendo potenciadores de la permeación y diferentes concentraciones de ketoconazol. Se determinó la estabilidad, la toxicidad y la actividad anti-Leishmania in vitro. Además, se evaluó in vivo la efectividad de las formulaciones aplicadas tópicamente en ratones con LC infectados con Leishmania (Viannia) braziliensis. Las formulaciones tipo crema fueron evaluadas adicionalmente en ratones infectados con L. (V.) panamensis. Los sistemas evaluados mantuvieron in vitro la actividad del ketoconazol contra los parásitos; sin embargo, ninguna de las formulaciones fue efectiva en curar las lesiones de LC en los ratones. El tratamiento tópico con miltefosina (utilizado como control) curó las lesiones. Se concluye que las formulaciones que contienen ketoconazol diseñados en este estudio, no fueron efectivos contra la LC en los ratones infectados.
