In this paper we present selected members of 7 new series of bent-shaped five-ring resorcinol derivatives which are distinguished by substituents at the central core as well as at the outer rings. Depending on the kind and position of the substituents and depending on the length of the terminal chains not only have new mesophases (the C-PA phase or three unidentified B-2-like phases) been identified, but also interesting phase sequences have been observed (B-2-N; B-2-SmA; B-2-SmA-SmC; B-2-SmA-SmC-N).

In the design of potent and selectivesphingosine-1-phosphatereceptoragonists, we were able to identify two series of molecules based on phenylamide and phenylimidazole analogs of FTY-720. Several designed molecules in these scaffolds have demonstrated selectivity for S1Preceptor subtype 1 versus 3 and excellent in vivo activity in mouse. Two molecules PPI-4621 (4b) and PPI-4691 (10a), demonstrated
