    The fundamental reason is the lack of head-to-head clinical trials providing inter- and intragroup comparisons between PAMORAs, laxatives, and secretagogue agents. These investigations must be accompanied by further valid biopharmaceutical and economic evaluations, paving the way for rational clinical judgment in each context.

    Journal:  A New Regioselective Synthesis of the Cysteine-Rich Peptide Linaclotide. (Pubmed Central) -  Feb 12, 2023   
    Linaclotide is a 14-amino acid residue peptide approved by the FDA for the treatment of irritable bowel syndrome with constipation (IBS-C), which activates guanylate cyclase C to accelerate intestinal transit. Here we show a new method for the synthesis of linaclotide through the completely selective formation of three disulfide bonds in satisfactory overall yields via mild oxidation reactions of the solid phase and liquid phase, using 4-methoxytrityl (Mmt), diphenylmethyl (Dpm) and 2-nitrobenzyl (O-NBn) protecting groups of cysteine as substrate, respectively.

    Journal:  Phosphine-Dependent Photoinitiation of Alkyl Thiols under Near-UV Light Facilitates User-Friendly Peptide Desulfurization. (Pubmed Central) -  Jan 6, 2023   
    We highlight the utility of this approach for desulfurization of industrially relevant targets including cyclic peptides and glucagon-like peptide 1 (GLP-1(7-36)). The method is also compatible with NCL buffer, and we highlight the robustness of the approach through the one-pot disulfide reduction/multidesulfurization of linaclotide, aprotinin, and wheat protein.

    Journal:  Intestinal neuropod GUCY2C regulates visceral pain. (Pubmed Central) -  Dec 23, 2022   
    Importantly, eliminating GUCY2C selectively in neuropod cells also increased nociceptive signaling and VP that was refractory to linaclotide. In the context of loss of GUCY2C hormones in patients with VP, these observations suggest a specific role for neuropod GUCY2C signaling in the pathophysiology and treatment of these pain syndromes.

    Because of the complex nature of absorption, distribution, metabolism, and excretion in the aging population, all agents used to treat OIC must be evaluated individually and reevaluated as patients continue to age. This review will serve as a guide to managing OIC in older adults.

    In addition, relamorelin, a ghrelin agonist, seems promising for accelerating colonic transit...On the other hand, the experience with these new agents is still limited, especially for long-term treatment. Another important point is that these new treatments for chronic idiopathic constipation are not available worldwide and their use could be somewhat limited by their still relatively high cost.

    Although treatment responses with linaclotide occurred in >50% of patients with IBS-C within 4 weeks of treatment initiation, benefits for individual abdominal symptoms and/or CSBM frequency can still occur between 4 and 12 weeks. A lack of improvement in one symptom does not negate the possibility of response for others, highlighting the importance of discussing all symptoms with patients and not assuming treatment futility at 4 weeks.

    Neuropod mediated changes to DRG electrical properties potentially play a role in the pathophysiology of visceral abdominal pain (SDCC Halls B-H) -  Oct 10, 2022 - Abstract #Neuroscience2022NEUROSCIENCE_8527;    
    Supporting this role, the synthetic GUCY2C agonist linaclotide has significant analgesic effects in CVP...These results strongly suggest a new pathway of visceral pain signaling involving GUCY2C-high neuropod EECs that communicate with DRG neurons to regulate their intrinsic excitability and thereby nociceptive signaling. Therefore, GUCY2C-high neuropod EECs emerge as therapeutic targets to develop new interventions to treat CVP.

    Further, it is universally expressed in advanced metastatic colorectal tumors, as well as other cancer types that arise through intestinal metaplasia. In this context, GUCY2C satisfies many characteristics of a compelling target and biomarker for gastrointestinal malignancies.
