In 1925, J. B. Collip (1925) reported that extracts of parathyroid gland contained an activity that raised calcium levels in the blood of parathyroidectomized animals, and suggested that this was due to a hormone produced in the parathyroid gland. The story of parathyroid hormone discovery was indicative of ever-increasing sophistication in sample preparation and protein isolation techniques. This paper resolved earlier controversies over the function of the parathyroid glands and c- trol of blood calcium. The year 1961 was a banner year for parathyroid research, in which the peptides parathyroid hormone and calcitonin were purified, and in which it was suggested that calcitonin could lower blood calcium (Copp and Cameron 1961). In 1982 it was discovered that in neurons the primary RNA transcript for calcitonin could be alternatively-spliced to give calcitonin gene-reated peptide (CGRP), and shortly thereafter amylin (previously named islet amyloid polyp- tide, IAPP) was identified and shown to have homology to CGRP. Since then a and b CGRP have been delineated and adrenomedullin and intermedin discovered, and this family of homologous peptides has emerged. This family of peptide hormones has a diverse and constantly expanding range of important physiologic functions, including regulation of blood calcium, vascular tension, feeding behavior and pain recognition.

Intended to promote a more appropriate and modern therapeutic approach to migraine management, this book is the first to deal with monoclonal antibodies in this context. Authored by the most respected migraine experts from around the globe and drawing on the lessons learned in both clinical trials and clinical practice, it reviews the current state of knowledge on this important therapeutic innovation, which has produced impressive data in randomized controlled trials, and the efficacy and safety of which have been confirmed in day-to-day real-world use. Given its scope, the book will appeal to a broad range of specialists, including pharmacologists, clinical pharmacologists, neurologists and internists, but also to residents and medical students.

Calcitonin gene-related peptide (CGRP) is a 37 amino-acid neuropeptide that initiates intracellular signalling through binding and activation of a group of calcitonin-family class B G protein-coupled receptors (GPCR). The canonical receptor for CGRP is the heteromeric CGRP receptor, comprised of the calcitonin receptor-like receptor (CLR) in complex with receptor activity-modifying protein 1 (RAMP1). CGRP is primarily expressed in nociceptive sensory neurons that innervate peripheral tissues. CGRP displays pleiotropic biological effects that include vasodilation, inflammation, pain transmission and energy homeostasis. As CGRP activity is implicated in a variety of dysregulated conditions, the development of therapeutics that modulate or block CGRP action is an active area of research. The first developed small molecule antagonists such as olcegepant and telcagepant displayed nanomolar affinity but were discontinued due to poor oral bioavailability and liver toxicity issues respectively. However, this set the stage for the development of more successful CGRP inhibitors such as the monoclonal antibody -ubrogepant. At present, several humanised monoclonal antibodies such as erenumab and fremanezumab have shown clinical efficacy for migraine treatment and are approved by the FDA as therapeutics. Another potential therapeutic strategy is to develop peptides to block CGRP action. However, peptides typically have short half-life in vivo, which limits their utility as therapeutics for clinical use. To counteract this drawback, modifications such as lipidation can be employed to extend peptide half-life. This thesis focuses on CGRP8-37, which is a truncated form of CGRP lacking the first seven residues. CGRP8-37 is a competitive antagonist at both CGRP and Amylin 1 (AMY1) receptors, which is also responsive to CGRP. The aim was to investigate the pharmacology and biological action of lipidated analogues based on CGRP8-37 to ascertain their therapeutic potential as peptide-based antagonists of CGRP action. Chapter 3 investigates the antagonist activities of several cysteine-substituted and palmitoylated analogues based on CGRP8-37 or CGRP7-37 across several calcitonin-family receptors expressed in transiently transfected Cos-7 cells. Chapter 4 describes further characterisation of the analogues’ antagonist activities at CGRP and AMY1 receptors as well as the CGRP receptor endogenously expressed in SK-N-MC cells. Chapter 5 describes the establishment and validation of a Laser doppler technique to investigate vasodilatory action by endogenous CGRP release in vivo. Selected lipidated peptide antagonists were investigated for their ability to attenuate this response and therefore discern its CGRP antagonist activity in vivo. Findings show that palmitoylation improved antagonist activity across both CGRP and AMY1 receptors, as well as several other calcitonin family receptors. The antagonist activity of the lipidated peptides exhibited hemi-equilibrium characteristics suggesting altered binding kinetics. The lipidated peptide analogues, V8C-palmitate and K24C-palmitate, were tested in vivo and showed inhibition of CGRP action as measured through suppression of capsaicin-induced dermal vasodilatory responses in mice. Overall, these findings support lipidation as a viable option to develop CGRP peptide antagonists as potential therapeutics.

This book is designed to focus on the role of Calcitonin Gene-Related Peptide (CGRP) in health and disease. This peptide, originally discovered in the 1980s as a sensory neuropeptide with cardiovascular effects, is now known to play a distinct role in the pain processing of migraine. The various chapters address the origin, localization and function of CGRP and its receptor in the peripheral nervous system, in the cardiovascular system, and in other tissues and organs. Further attention is paid to the drug discovery pathway where recent findings show the beneficial effect of small molecule antagonists of the CGRP receptors for the relief of the migraine attack and of monoclonal antibodies against CGRP or the CGRP receptor for migraine prevention.

The Chemistry and Biology of Nitroxyl (HNO) provides first-of-its-kind coverage of the intriguing biologically active molecule called nitroxyl, or azanone per IUPAC nomenclature, which has been traditionally elusive due to its intrinsically high reactivity. This useful resource provides the scientific basis to understand the chemistry, biology, and technical aspects needed to deal with HNO. Building on two decades of nitric oxide and nitroxyl research, the editors and authors have created an indispensable guide for investigators across a wide variety of areas of chemistry (inorganic, organic, organometallic, biochemistry, physical, and analytical); biology (molecular, cellular, physiological, and enzymology); pharmacy; and medicine. This book begins by exploring the unique molecule’s structure and reactivity, including important reactions with small molecules, thiols, porphyrins, and key proteins, before discussing chemical and biological sources of nitroxyl. Advanced chapters discuss methods for both trapping and detecting nitroxyl by spectroscopy, electrochemistry, and fluorescent inorganic cellular probing. Expanding on the compound’s foundational chemistry, this book then explores its molecular physiology to offer insight into its biological implications, pharmacological effects, and practical issues. Presents the first book on HNO (nitroxyl or azanone), an increasingly important molecule in biochemistry and pharmaceutical research Provides a valuable coverage of HNO’s chemical structure and significant reactions, including practical guidance on working with this highly reactive molecule Contains high quality content from recognized experts in both industry and academia
