Cryptococcus neoformans, an encapsulated fungal pathogen is evolving as a major threat to immune-compromised patients and rarely to healthy individuals also. The cell wall bound capsular polysaccharide, melanin pigment and biofilm formation are major virulence factors that are known to contribute to cryptococcal meningitis. In the present study, a furanone derivative, (E)-5-benzylidenedihydrofuran-2(3H)-one (compound-6) was evaluated against biofilm of seven different strains of C. neoformans in melanized and non-melanized condition. In addition, the efficacy of compound-6 in activation of TLR-2, opsonophagocytosis, and modulation of cytokine expression during phagocytosis were studied. During the biofilm study, we found that moderate capsule size favored biofilm formation. Interestingly, the minimum biofilm eradication concentration (MBEC_0.5) of melanized biofilm was found to be achieved at 1- to 1.7-fold higher MBEC_0.5 of non-melanized cells. The maximum eradication of 77% and 69% of non-melanized and melanized biofilm were observed. The capsule size was reduced to half of its size with marked changes in morphology. Furthermore, expression of TLR2, iNOS and pro-inflammatory cytokines such as TNF-α, IL-12, and IFN-γ were also facilitated by compound-6. The correlation analysis showed a positive correlation between phagocytosis and the expression of TLR-2, iNOS, IL-6, IL-12. Collectively, the significant effect of compound-6, anti-melanization activity, antibiofilmand effective immunomodulant could be an interesting dual strategy drug agonist against cryptococcal meningitis.
