Efficient and one-pot synthesis of novel sulfamates from carboxylic acids

Effective synthesis of novel sulfamates from various carboxylic acids has been developed in the presence of chlorosulfonyl isocyanate (CSI) in mild conditions. Several acids, bases and solvents effects were investigated for one-pot synthesis sulfamates as a catalyst. Finally, triflic acid was found to possess efficiently under optimized conditions in acetonitrile. This method is easy, fair price and practical. It can be synthesized on grams and milligrams scale.

Helquats: A facile, modular, scalable route to novel helical dications

The synthesis and properties of helical extended diquat (helquat), and derivatives that bear resemblance to diquat and azoniahelicene, was reported. Triyne with elongated tethers connecting the heterocyclic moiety with the pendant alkyne functionalities undergoing cycloisomerization give helquat featuring two seven-membered rings. The seven helquats reported are accessed uniformly in three steps from commercially available starting materials, entailing a Sonogashira coupling, bisquaternization, cycloisomerization, and [2+2+2] cycloisomerization. The evidence for the reversible electrochemical Weiz-type manifold and regular columnar stacks in crystal structures suggest the potential of helquats as electroactive functional elements.

Design, synthesis, and evaluation of novel small molecule inhibitors of the influenza virus protein NS1

Influenza is a continuing world-wide public health problem that causes significant morbidity and mortality during seasonal epidemics and sporadic pandemics. The existing vaccination program is variably effective from year to year, and drug resistance to available antivirals is a growing problem, making the development of additional antivirals an important challenge. Influenza virus non-structural protein 1 (NS1) is the centerpiece of the viral response to the host interferon (IFN) system. NS1 was demonstrated previously to be a potential therapeutic target for antiviral therapy by the identification of specific small-molecule inhibitors. One inhibitory compound, NSC125044, was subjected to chemical evaluation. Initial synthetic work comprised simplifying the core structure by removing unwanted functionality and determination of key features important for activity. Several subclasses of molecules were designed and synthesized to further probe activity and develop the basis for a structure-activity relationship. Apparent potency, as judged by activity in virus replication assays, increased dramatically for some analogs, without cytotoxicity. Results suggest that the target binding site tolerates hydrophobic bulk as well as having a preference for weakly basic substituents.

Synthesis and pharmacological evaluation of potent and highly selective D3 receptor ligands: Inhibition of cocaine-seeking behavior and the role of dopamine D3/D2 receptors

The synthesis, pharmacological evaluation, and structure – activity relationships (SARs) of a series of novel arylalkylpiperazines structurally related to BP897 (3) are described. In binding studies, the new derivatives were tested against a panel of dopamine, serotonin, and noradrenaline receptor subtypes. Focusing mainly on dopamine D3 receptors, SAR studies brought to light a number of structural features required for high receptor affinity and selectivity. Several heteroaromatic systems were explored for their dopamine receptor affinities, and combinations of synthesis, biology, and molecular modeling, were used to identify novel structural leads for the development of potent and selective D3 receptor ligands. Introduction of an indole ring linked to a dichlorophenylpiperazine system provided two of the most potent and selective ligands known to date (D 3 receptor affinity in the picomolar range). The intrinsic pharmacological properties of a subset of potent D3 receptor ligands were also assessed in [35S]-GTPgammaS binding assays. Evidence from animal studies, in particular, has highlighted the dopaminergic system’s role in how environmental stimuli induce drug-seeking behavior. We therefore tested two novel D3 receptor partial agonists and a potent D 3-selective antagonist in vivo for their effect in the cocaine-seeking behavior induced by reintroduction of cocaine-associated stimuli after a long period of abstinence, and without any further cocaine. Compound 5g, a nonselective partial D3 receptor agonist with a pharmacological profile similar to 3, and 5p, a potent and selective D 3 antagonist, reduced the number of active lever presses induced by reintroduction of cocaine-associated stimuli. However, 5q, a highly potent and selective D3 partial agonist, did not have any effect on cocaine-seeking behavior. Although brain uptake studies are needed to establish whether the compounds achieve brain concentrations comparable to those active in vitro on the D3 receptor, our experiments suggest that antagonism at D2 receptors might significantly contribute to the reduction of cocaine craving by partial D3 agonists.
