Write answer in between .Q:An 11-year-old boy with HIV and esophageal candidiasis is being treated with caspofungin. What is the mechanism of action of this drug?? A: Pore formation in cell membranes, B: Inhibition of ergosterol synthesis, C: Inhibition of squalene epoxidase, D: Inhibition of pyrimidine synthesis, E: Inhibition of 1,3-Beta-glucan synthase,  <response>: This is a question about the mechanism of action of the antifungal drug caspofungin in a patient with HIV and esophageal candidiasis. Caspofungin is an echinocandin antifungal that inhibits the enzyme 1,3-beta-glucan synthase, which is involved in fungal cell wall synthesis. Candida species have a cell wall composed of glucans and inhibiting its synthesis leads to osmotic instability and cell lysis. So the correct answer should be the one that mentions inhibition of 1,3-beta-glucan synthase.E: Inhibition of 1,3-Beta-glucan synthase
