The present invention relates to the treatment of dopamine-related dysfunction using full D1 dopamine receptor agonists in an intermittent dosing protocol with a short, but essential, ?off-period.? The D1 agonist concentration is reduced during the ?off-period? to obtain a plasma concentration of agonist that suboptimally activates D1 dopamine receptors for a period of time to prevent induction of tolerance. Specifically, the method comprises the steps of periodically administering to a patient a full D1 agonist with a half-life of up to about 6 hours at a dose resulting in a first plasma concentration of agonist capable of activating D1 dopamine receptors to produce a therapeutic effect. The dose is reduced at least once every 24 hours to obtain a second lower plasma concentration of agonist that results in suboptimal activation of D1 dopamine receptors for a period of time sufficient to prevent induction of tolerance.

Asymmetric reduction of prochiral cyclic imines with chiral sodium acyloxyborohydrides (5a-i), which are easily prepared by the reaction of NaBH4 with various N-acyl alpha-amino-acids, has been investigated.Of these new reducing agents, triacyloxyborohydrides (5c-f), derived from NaBH4 (1 equiv.) and (S)-N-acylproline (3 equiv.), were found to reduce 3,4-dihydropapaverine (2) in tetrahydrofuran to (S)-norlaudanosine (3) hydrochloride in 60percent optical yield.The N-benzyloxycarbonyl derivative (5c) could be isolated as a powder and characterized.The effect of solvents on this asymmetric reduction has been examined by the use of the isolated reagent (5c); halogenated alkane solvents such as CH2Cl2 or CHCl2CH3 gave a better optical yield of compound (3) (79percent e.e.).The reagent (5c) also reduced other cyclic imines (6a-c) and (8) to the corresponding alkaloids (7a-c) and (9) in excellent optical yields (70-86percent e.e.), providing an effective route to the asymmetric synthesis of these alkaloids.A possible reaction path for this reduction is also presented.

Full details are provided for an improved synthesis of cortistatin A and related structures as well as the underlying logic and evolution of strategy. The highly functionalized cortistatin A-ring embedded with a key heteroadamantane was synthesized by a simple and scalable five-step sequence. A chemoselective, tandem geminal dihalogenation of an unactivated methyl group, a reductive fragmentation/trapping/elimination of a bromocyclopropane, and a facile chemoselective etherification reaction afforded the cortistatin A core, dubbed “cortistatinone”. A selective delta16-alkene reduction with Raney Ni provided cortistatin A. With this scalable and practical route, copious quantities of cortistatinone, delta16-cortistatin A (the equipotent direct precursor to cortistatin A), and its related analogues were prepared for further biological studies.

Structure-activity relationships have been developed around 5-bromo-8-toluylsulfonamidoquinoline 1 a hit compound in an assay for the interaction of the E3 ligase Skp2 with Cks1, part of the SCF ligase complex. Disruption of this protein-protein interaction results in higher levels of CDK inhibitor p27, which can act as a tumor suppressor. The results of the SAR developed highlight the relationship between the sulfonamide and quinoline nitrogen, while also suggesting that an aryl substituent at the 5-position of the quinoline ring contributes to the potency in the interaction assay. Compounds showing potency in the interaction assay result in greater levels of p27 and have been shown to inhibit cell growth of two p27 sensitive tumor cell lines.

Mediators play a central role in Catellani-type reactions. Herein we reported the discovery of inexpensive 5-norbornene-2-carboxylic acid (N4) as a general catalytic mediator (20 mol%) to facilitate ortho C?H activation and the following C?C bond formation of aryl iodides. Firstly, a cooperative catalytic system comprising N4 and a palladium/XPhos complex was developed for the novel Catellani/redox-relay Heck cascade to construct tetrahydronaphthalenes and indanes that contain a quaternary carbon stereogenic center. The striking feature of this work was the avoidance of stoichiometric NBE mediator that are usually required for Catellani-type reactions. Then, preliminary results demonstrated that N4 could act as a general catalytic mediator to replace NBE for other Catellani-type reactions, which will undoubtedly inspire future developments in the field of cooperative catalysis. Finally, control experiments indicated that the carboxylic acid moiety of N4 plays an essential role in its ability to serve as a superior mediator.
