SOLUBLE COMBINATORIAL LIBRARIES
-
, (2008/06/13)
The present invention relates to novel soluble combinatorial libraries, comprising a soluble phase in solution attached to a core molecule, and allowing the improved high-yield and efficient production of soluble combinatorial libraries. Some specific examples of the soluble combinatorial libraries claimed herein comprise one or more of the following: amino acids, α-azetide amino acids, triazine dione molecules, γ-lactamtide molecules, δ-lactamthiotide molecules, β-lactam nucleus containing molecules, lycoramine alkaloid nucleus containing molecules, and β-blocker nucleus molecules. Further, a split synthesis technique for generating libraries of combinatorial molecules employs a biphasic macromolecular support which is soluble during the pooling, splitting, and coupling steps but which is insoluble during the washing step. The use of a biphasic macromolecular support in its soluble phase significantly enhances the efficiency and performance of the pooling, splitting, and coupling steps. The use of a biphasic macromolecular support in its insoluble phase significantly enhances the efficiency and performance of the washing step.

, p. 2163 - 2168 (2007/10/03)
The composition of products of the interaction of asymmetric fluoroalkyl-containing β-diketones with amines was studied. Mixtures of regioisomeric β-aminovinylketones and products of cleavage and secondary condensation are formed, depending on the temperature, the solvent, the nature of the fluorinated and nonfluorinated substituents in the β-diketone, and the basicity of the amine. The major product is a β-aminovinylketone in which the NH2 group is removed from the fluoroalkyl substituent. No β-aminovinylimines, products of condensation involving two electrophilic centers, were observed.
NEW MESO-AZACYCLIC AROMATIC ACID AMIDES AND ESTERS AS NOVEL SEROTONERGIC AGENTS
-
, (2008/06/13)
The meso-azacyclic aromatic acid amides and esters of the present invention are useful in the treatment of the central nervous system and gastrointestinal motility disorders such as gastroesophageal reflux, non-ulcer dyspepsia, delayed gastric emptying, ileus, irritable bowel syndrome, and the like. Additionally, the compounds of the present invention find utility as antagonists of serotonin 5-HT 3 receptors. As such they are useful for the treatment of humans and animals wherein antagonism of 5-HT 3 receptors is beneficial. Therapy is indicated for, but not limited to, the treatment of anxiety, psychoses, depression (especially depression accompanied by anxiety), cognitive disorders, substance abuse dependence and/or withdrawal, irritable bowel syndrome, emesis caused by chemotherapeutic agents, and visceral pain. Additionally, the compounds of the present invention may find utility as enhancers of nasal absorption of bioactive compounds.

Amine Catalysis of the Hydrolysis of Trifluoroacetanilide
Huffman, Robert W.
, p. 2675 - 2680 (2007/10/02)
Only hydrolysis products could be isolated from the reaction of trifluoroacetanilide I with aqueous n-butylamine buffer at pH 10.5.Kinetic studies of the decomposition of trifluoroacetanilide I in aqueous morpholine, n-butylamine, piperidine and trimethylamine buffers were also conducted.The most reasonable scheme for the reaction mechanism, compatible with all data, is presented in Scheme I and involves the general-base-catalyzed decomposition of the intermediate III which can be formed by hydroxide ion or water addition to I.Utilizing the constants of Table I, eq 6 is capable of predicting observed rate constants with an error of l ess than 9 percent (see Tables II an III).Some variation in values for these constants for trimethylamine buffers is observed and attributed to possible activity changes for the solutions.Deuterium isotope rate effects were determined for these constants in morpholine buffers.A value of k1H2O/k2D2O of 0.39 was obtained and may indicate the presence of a third pathway for the generation of III (eq 9), involving the hydration of the anion II.A value of k4H2O/k4D2O of 1.65 and a Broensted β value of 0.23 for k4 are interpreted to indicate general-base catalysis by the amine buffer.The low values for these quantities are indicative of a transition state involving an early proton transfer.General-base catalysis of proton transfer for the k4 step is also indicated by the fact that trimethylamine appears to behave mechanistically, similar to the other amines used.The value of 8.8 obtained for k3H2O/k3D2O clearly shows proton transfer to be occuring in this step as well.The results of this study thus support those suggested previously in that the hydrolysis of I undergoes a change in rate-determining step in mild alkaline aqueous solutions.This occurs because of the combination of the poor leaving ability of the anilinium ion and acyl activation present in the substrate trifluoroacetanilide.
