Sivifene
Sivifene is the phenylhydrazone 4,4'-dihydroxybenzophenone-2,4-dinitrophenylhydrazone formulated as a topical agent with immunomodulating and potential antineoplastic activities. Applied topically as a gel, sivifene may stimulate a local immune response against human papillomavirus (HPV)-induced cervical intraepithelial neoplasia (CIN).
