α-Cyclodextrin complexation of 3-O2NC6H4O(CH2)nNH2 inhibits by 40 and 15%, respectively, the efficiency of base-catalyzed and uncatalyzed photo-Smiles rearrangement for n = 2; α-CD complexation inhibits the photorearrangement efficiency of n = 3 by 40% in the base-catalyzed regime but enhances the efficiency by 67% in the uncatalyzed regime.
The present invention is directed to pyridazinone compounds of formula (I) and furan compounds of formula (II), pharmaceutical compositions of compounds of formula (I) and (II), kits containing these compounds, methods of syntheses, and a method of treatment of a proliferative disease in a subject by administration of a therapeutically effective amount of a compound of formulae (I) or (II). Both classes of compounds were identified through screening of a collection of small molecule libraries.

A series of 2-(aminomethyl)chromans (2-AMCs) was synthesized and evaluated for their affinity and selectivity for both the high-and low-affinity agonist states (D-2(High) and D-2(Low), respectively) of the dopamine (DA) D-2 receptor. The 7-hydroxy-2-(aminomethyl)chroman moiety was observed to be the primary D-2 agonist pharmacophore. The 2-methylchroman moiety was discovered to be an entirely novel scaffold which could be used to access the D-2 agonist pharmacophore. Attaching various simple alkyl and arylalkyl side chains to the 7-hydroxy 2-AMC nucleus had significant effects on selectivity for the D-2(High) receptor vs the 5HT(1A) and alpha(1) receptors. A novel DA partial agonist, (R)-(-)-2-(benzylamino)methyl)chroman-7-ol [R-(-)-35c], was identified as having the highest affinity and best selectivity for the D-2(High) receptor vs the alpha(1) and 5HT(1A) receptors. Several regions of the 2-AMC nucleus were modified and recognized as potential sites to modulate the level of intrinsic activity. The global minimum conformer of the 7-hydroxy-2-AMC moiety was identified as fulfilling the McDermed model D-2 agonist pharmacophoric criteria and was proposed as the D-2 receptor-bound conformation. Structure-activity relationships gained from these studies have aided in the synthesis of D-2 partial agonists of varying intrinsic activity levels. These agents should be of therapeutic value in treating disorders resulting from hypo-and hyperdopaminergic activity, without the side effects associated with complete D-2 agonism or antagonism.
