Discovery of Soft-Drug Topical Tool Modulators of Sphingosine-1-phosphate Receptor 1 (S1PR1)

In order to study the role of S1PRs in inflammatory skin disease, S1PR modulators are dosed orally and topically in animal models of disease. The topical application of S1PR modulators in these models may, however, lead to systemic drug concentrations, wh

PROCESS FOR THE PREPARATION OF|(2Z,5Z)-5-(3-CHLORO-4-((R)-2,3-DIHYDROXYPROPOXY)BENZYLIDENE)-2-(PROPYLIMINO)-3-|(O-TOLYL)THIAZOLIDIN-4-ONE AND INTERMEDIATE USED IN SAID PROCESS

The present invention relates to a new process for the preparation of (2Z,5Z)-5-(3-chloro-4- ((R)-2,3-dihydroxypropoxy)benzylidene)-2-(propylimino)-3-(o-tolyl)thiazolidin-4-one and to the new intermediate (R)-3-chloro-4-(2,3-dihydroxypropoxy)-benzaldehyde used in this process. (2Z,5Z)-5-(3-Chloro-4-((R)-2,3-dihydroxypropoxy)benzylidene)-2-(propylimino)-3- (o-tolyl)thiazolidin-4-one is described in WO 2005/054215 to act as an immunosuppressive agent. The present invention further also relates to a new process for the preparation of (R)-3-chloro-4-(2,3-dihydroxypropoxy)-benzaldehyde.

2-Imino-thiazolidin-4-one derivatives as potent, orally active S1P 1 receptor agonists

Sphingosine-1-phosphate (S1P) is a widespread lysophospholipid which displays a wealth of biological effects. Extracellular S1P conveys its activity through five specific G-protein coupled receptors numbered S1P1 through S1P5. Agonists of the S1P1 receptor block the egress of T-lymphocytes from thymus and lymphoid organs and hold promise for the oral treatment of autoimmune disorders. Here, we report on the discovery and detailed structure-activity relationships of a novel class of S1P1 receptor agonists based on the 2-imino-thiazolidin-4-one scaffold. Compound 8bo (ACT-128800) emerged from this series and is a potent, selective, and orally active S1P1 receptor agonist selected for clinical development. In the rat, maximal reduction of circulating lymphocytes was reached at a dose of 3 mg/kg. The duration of lymphocyte sequestration was dose dependent. At a dose of 100 mg/kg, the effect on lymphocyte counts was fully reversible within less than 36 h. Pharmacokinetic investigation of 8bo in beagle dogs suggests that the compound is suitable for once daily dosing in humans.

NEW PROCESS FOR THE PREPARATION OF 2-IMINO-THIAZOLIDIN-4-ONE DERIVATIVES

The present invention relates to a new process for the preparation of 2-imino- thiazolidin-4-one compounds of the Formula (I) and (II) and to compounds of Formula (II) as such. The present compounds of Formula (II) can be used as intermediates in the preparation of thiazolidin-4-one derivatives of the General Formula (II), said derivatives being described in WO 2005/054215. These compounds of General Formula (II) are described in WO 2005/054215 to act as immunosuppressive agents.
