Abstract: This invention provides a method to identify compounds potentially useful for the treatment and prevention of neoplasia in mammals. The phosphodiesterase inhibitory activity of a compound is determined along with its ability to elevate JNK kinase activity. Growth inhibitory and apoptosis inducing effects on cultured tumor cells are also determined. Compounds that exhibit phosphodiesterase inhibition, an ability to elevate JNK kinase activity, growth inhibition and apoptosis induction are desirable for the treatment of neoplasia.

Abstract: Derivatives of 2-phenyl quinazolinones are useful for the treatment of patients having precancerous lesions. These compounds are also useful to inhibit growth of neoplastic cells.
Abstract: This invention provides a method for treating a patient with neoplasia by an adjuvant therapy that includes treatment with an antineoplastic vinca alkaloid derivative.
Abstract: This invention provides pharmaceutical compositions containing compounds for the treatment of neoplasia in mammals. The phosphodiesterase inhibitory activity of a compound is determined along with COX inhibitory activity. Growth inhibitory and apoptosis inducing effects on cultured tumor cells are also determined. Compounds that exhibit phosphodiesterase inhibiton, growth inhibition and apoptosis induction, but prefereably not substantial prostaglandin inhibitory activity, are desirable for the treatment of neoplasia.
Abstract: A method for inhibiting neoplasia, particularly cancerous and precancerous lesions by exposing the affected cells to isoquinoline derivatives.
Abstract: [4,5]-Fused-3,6 disubstituted-pydidazines of Formula I are useful for inducing or promoting apoptosis and for arresting uncontrolled neoplastic cell proliferation, and are specifically useful in the arresting and treatment of neoplasia:
wherein
Y1 and Y2 are independently selected from the group consisting of (CH2)n,—C(X)—NH—,—(CH2)n—C(X)—O—, and X is O or S;
R1 is selected from the group consisting of lower alkyl, lower alkenyl, lower alkynyl, and substituted or unsubstituted phenyl, pyridinyl, and the like;
R2 is selected from the group consisting of substituted or unsubstituted phenyl, benzyl, pyridinyl, and the like;
“A” is a benzene ring fused with the pyridazine ring; and
R3 is independently selected in each instance form the group consisting of halogen, lower alkyl, and the like.
