Vulvar candidiasis (VVC) is a vaginitis caused by vaginal mucosa infection of Candida, which greatly impairs women's health. Although there are more and more thiazoles on the market, new classes of antifungal drugs are still missing, it is still challenging to treat azole-resistant candidal vaginitis. We found that L-Se-methylselenocysteine (L-SeMC) could effectively inhibit the growth of Candida albicans, reduce the density and length of the mycelia. To extend the retention time of L-SeMC in the vaginal tract and enhance its therapeutic effect for VVC, a mucoadhesive thermogel (NAC-HA thermogel) was successfully synthesized and prepared. The gelation window was around 29-56 °C for L-SeMC loaded mucoadhesive thermogel (L-SeMC@NAC-HA thermogel), which exhibited a sustained release profile in the in vitro release study and an extended retention time in the vaginal tract. Besides, L-SeMC@NAC-HA thermogel exhibited a good safety profile in the in vivo safety study. The in vivo anti-VVC effect was examined in a rat VVC model and L-SeMC@NAC-HA thermogel significantly reduced the number of Candida albicans in the vaginal secreta, mitigated the vaginal damage and reduced the secretion of proinflammatory factors (TNF-α, IL-1α and IL-ß). Therefore, it is a promising therapy for the clinical treatment of VVC in the near future.
