TIE1 and TIE2 receptor tyrosine kinases inversely regulate embryonic angiogenesis by the mechanism of intussusceptive microvascular growth

This work is a sequel to and completes the review, that recently appeared in this journal, of pentatomic cyclic muscarinic agonists. It reports the results of structure-activity relationship (SAR) studies of pentatomic cyclic antagonists on muscarinic receptors and compares these results with some recent advances in molecular biology and quantitative structure-activity relationship (QSAR) studies.
