- Synthesis method of lifitegrast intermediate
-
The invention provides a preparation method of a lifitegrast intermediate I. The method comprises steps as follows: 6-bromobenzo[b]furan is taken as a starting raw material and subjected to a halogen-lithium exchange reaction under the action of n-butyllithium, a product is subjected to a reaction with dimethyl carbonate, methyl benzofuran-6-carboxylate is prepared and hydrolyzed, and the lifitegrast intermediate I is obtained. The raw materials are cheap and easily available, few reaction by-products are produced, yield and purity of a final product are high, meanwhile, the step (1) an the step (2) can be subjected to the one-pot reaction, so that steps of the reaction are simplified, furthermore, the reaction conditions are mild, the product does not need separation on columns, and industrialization is easy to realize.

- Discovery and development of potent LFA-1/ICAM-1 antagonist SAR 1118 as an ophthalmic solution for treating dry eye
-
LFA-1/ICAM-1 interaction is essential in support of inflammatory and specific T-cell regulated immune responses by mediating cell adhesion, leukocyte extravasation, migration, antigen presentation, formation of immunological synapse, and augmentation of T-cell receptor signaling. The increase of ICAM-1 expression levels in conjunctival epithelial cells and acinar cells was observed in animal models and patients diagnosed with dry eye. Therefore, it has been hypothesized that small molecule LFA-1/ICAM-1 antagonists could be an effective topical treatment for dry eye. In this letter, we describe the discovery of a potent tetrahydroisoquinoline (THIQ)-derived LFA-1/ICAM-1 antagonist (SAR 1118) and its development as an ophthalmic solution for treating dry eye.

- Discovery of N-[(3R)-1-azabicyclo[2.2.2]oct-3-yl]furo[2,3-c]pyridine-5- carboxamide, an agonist of the α7 nicotinic acetylcholine receptor, for the potential treatment of cognitive deficits in schizophrenia: Synthesis and structure-activity relationship
-
N-[(3R)-1-Azabicyclo[2.2.2]oct-3-yl]furo[2,3-c]pyridine-5-carboxamide (14, PHA-543,613), a novel agonist of the α7 neuronal nicotinic acetylcholine receptor (α7 nAChR), has been identified as a potential treatment of cognitive deficits in schizophrenia. Compound 14 is a potent and selective a7 nAChR agonist with an excellent in vitro profile. The compound is characterized by rapid brain penetration and high oral bioavailability in rat and demonstrates in vivo efficacy in auditory sensory gating and, in an in vivo model to assess cognitive performance, novel object recognition.

- Aminoalkylindoles: Structure - Activity Relationships of Novel Cannabinoid Mimetics
-
Aminoalkylindoles (AAIs) are a novel series of cannabinoid receptor ligands.In this report we disclose the structural features of AAIs which are important for binding to this receptor as measured by inhibition of binding of 3H>Win 55212-2 (5).Functional activity in the mouse vas deferens is also noted and used to distinguish agonists from potential antagonists.The key structural features for potent cannabinoid activity in this series are a bicyclic (naphthyl) substituent at the 3-position, a small (H) substituent at the 2-position, and an aminoethyl (morpholinoethyl) substituent at the 1-position.A 6-bromo analog, Win 54461 (31), has been identified as a potential cannabinoid receptor antagonist.Modeling experiments were done to develop a pharmacophore and also to compare AAI structures with those of classical cannabinoids.The fact that the cannabinoid AAIs arose out of work on a series of cyclooxygenase inhibitors makes sense now that an endogenous cannabinoid ligand has been identified which is a derivative of arachidonic acid.Because of their unique structures and physical properties, AAIs provide useful tools to study the structure and function of the cannabinoid receptor(s).
