We are investigating compounds that could be useful in the treatment of neoplastic lesions of the cervix by acting on the oncoprotein E6 of human papillomavirus-16. The E6 protein containstwopotential zinc-binding domains that are required for most of its functions. We have published tests that measure (i) the release of zinc ions after chemical alteration of the cysteine groups of these zinc-binding

The invention pertains to novel cyclin dependent kinase inhibitors (cdks) and specifically, but not exclusively, as inhibitors of cdk/cyclin complexes. As described herein, the inhibitors of this invention are capable of inhibiting the cell-cycle machinery and consequently may be useful in modulating cell-cycle progression, ultimately controlling cell growth and differentiation. Such compounds would be useful for treating subjects having disorders associated with excessive cell proliferation.

investigation in aqueous solution, 25.0 degrees C, ionic strength 0.2 (KCl). The reactions are followed spectrophotometrically at 210-270 nm (PClF) and at 310-400 nm (NPClF). Under amine excess, pseudo-first-order rate coefficients (k(obsd)) are obtained. From linear plots of k(obsd) vs free amine concentration, the second-order rate coefficients (k(N)) for aminolysis are obtained. For the aminolysis of both
