Heterocycles in Organic Synthesis: Their Synthesis and Applications: Synthesis of Novel Heterocycles and Unnatural Glycosyl Amino Acids with Their ... and Pharmaceutical Studies and Applications Reham F. Barghash

Based on the recorded pharmacological potencies of numerous substituted pyrimidines as antihyperlipemic and antihypertensive agents, synthesis of condensed and spiro bis-heterocyclic systems; oxazole-pyrimidines as well as pyrimido-oxazines; bearing a phosphonate substituent was undertaken. The bioassay indicated that some of the products have effect on the central nervous system (CNS), and other products have good selective anti-tumor activity and the structure-activity relationship (SAR) of new phosphonates has also been indicated. In addition, a new class of C-glycosyl amino acids bearing a thiourea segment as a linker has been designed and synthesized by addition of glycosylmethyl isothiocyanates to an amine-functionalized amino acid. The orthogonal set of protective groups makes these compounds suitable substrates for the co-translational modification of natural peptides. The study included the synthesis of a set of new sugar isothiocyanates and their coupling with the alanine derivative.
