Research progress on the structure and biological diversities of 2-phenylindole derivatives in recent 20 years. Bioorg Chem 2023; 132:106342. [PMID: 36621157 DOI: 10.1016/j.bioorg.2023.106342] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Revised: 12/05/2022] [Accepted: 01/02/2023] [Indexed: 01/05/2023]
Abstract
The privileged structure binds to multiple receptors with high affinity, which is helpful to the development of new bioactive compounds. Indole is classified as a privileged structure, which may be one of the most important structural categories in drug discovery. As a special subset of indole compounds, 2-phenylindole seems to be one of most promising forerunners of drug development. In this paper, 106 articles were referenced to review the structural changes, biological activities and structure-activity relationship of compounds in recent 20 years, and classified them according to their pharmacological activities, from several aspects, including anticancer, antibacterial, anti-inflammatory, analgesic, antiviral, anti-parasite, the biological activities target to central nervous system, et al. It also points out the importance of artificial intelligence (AI) technology in discovery of new 2-phenylindole compounds in a broader prospect. This review will provide some ideas for researchers to develop new indole drugs.

J Neurol Sci 2020; 420:117276.

Abstract
Sars-Cov-2 or Novel coronavirus infection (COVID-19) has become a global challenge, affecting elderly population at large, causing a burden on hospitals. It has been affecting the world from a health and economic perspective after its emergence since October 2019 at Wuhan province of China. Later on it became a pandemic, with aged people most affected. Surprisingly, the infants and children were not severely infected and mortality among them was reported infrequently. If they died it was due to some comorbidity or congenital heart problems. Why the rate of infection varies in different age groups around the world and what is the protective mechanism in children remains a mystery. Based on our neuropathological experience at the “Lino Rossi Research Center for the study and prevention of the unexpected perinatal death and Sudden Infant Death Syndrome (SIDS)” of the University of Milan, Italy, we hypothesize that the decreased severity of the disease in infants compared to the elderly may be due to alteration at neurotransmitter levels especially of the Substance P (SP) and of the spinal trigeminal nucleus in the brainstem that is responsible for its secretion. This neurotransmitter may be directly related to the respiratory illness as is in COVID-19 infection. It is responsible for the increased inflammation and the characteristic symptoms associated with this disease. It is the main switch that must be urgently turned off using the NK-1R antagonist which is the receptor of SP and responsible for its functionality, especially in the elderly. COVID-19 is the biggest public health crisis of recent times. Children are not significantly affected in the same way as adults by COVID-19. The infant's immune system might protect from the ‘cytokine storm’ of adults. Increased expression of substance P in brains is here proposed as a possible cause. Aprepitant could be a promising therapeutic approach to COVID-19 infection in adults.

Abstract
Chronic itch can be extremely devastating and, in many cases, difficult to treat. One challenge in treating itch disorders is the limited understanding of the multitude of chemical players involved in the communication of itch sensation from the peripheral to the central nervous system. Neuropeptides are intercellular signaling molecules that are known to be involved in the transmission of itch signals from primary afferent neurons, which detect itch in the skin, to higher-order circuits in the spinal cord and brain. To investigate the role of neuropeptides in transmitting itch signals, we generated two mouse models of chronic itch-Acetone-Ether-Water (AEW, dry skin) and calcipotriol (MC903, atopic dermatitis). For peptide identification and quantitation, we analyzed the peptide content of dorsal root ganglia (DRG) and dorsal horn (DH) tissues from chronically itchy mice using liquid chromatography coupled to tandem mass spectrometry. De novo-assisted database searching facilitated the identification and quantitation of 335 peptides for DH MC903, 318 for DH AEW, 266 for DRG MC903, and 271 for DRG AEW. Of these quantifiable peptides, we detected 30 that were differentially regulated in the tested models, after accounting for multiple testing correction (q ≤ 0.1). These include several peptide candidates derived from neuropeptide precursors, such as proSAAS, protachykinin-1, proenkephalin, and calcitonin gene-related peptide, some of them previously linked to itch. The peptides identified in this study may help elucidate our understanding about these debilitating disorders. Data are available via ProteomeXchange with identifier PXD015949.

Abstract
The G protein-coupled receptor (GPCR), neurokinin-1 receptor (NK1R), and its preferred ligand, substance P (SP), are reviewed in relationship to the immune system and selected infections. NK1R and SP are ubiquitous throughout the animal kingdom. This important pathway has unique functions in numerous cells and tissues. The interaction of SP with its preferred receptor, NK1R, leads to the activation of nuclear factor-kappa B (NF-κB) and proinflammatory cytokines. NK1R has two isoforms, both a full-length and a truncated form. These isoforms have different functional significances and differ in cell signaling capability. The proinflammatory signals modulated by SP are important in bacterial, viral, fungal, and parasitic diseases, as well as in immune system function. The SP-NK1R system is a major class 1, rhodopsin-like GPCR ligand-receptor interaction.

Abstract
There is a high incidence of life event stress, depression, and associated symptoms in individuals with HIV infection/AIDS. Psychological and psychiatric symptomatology in individuals with HIV and AIDS may be related to the progression of AIDS disease. The association between depression, anxiety, and stress with HIV disease progression suggests that neurobiologic and neurophysiologic factors have an important role in modulating HIV. The immune effects caused by changes in behavioral state or brain activity are affected, at least in part, through the neuroendocrine-immune pathways. Life stress and depression may be associated with altered blood levels of CNS-released neuropeptides, including substance P (SP). SP is a powerful immunomodulator which is a critical link between the nervous and immune system. We have investigated the role of the neuropeptide SP and its preferred receptor, neurokinin-1, in HIV infection and AIDS. There are compelling data from our laboratories, as well as the findings in the literature, which demonstrate that SP may play an important role in the pathophysiology of neuropsychiatric disorders, including stress and depression in HIV-infected individuals and in the immunopathogenesis of HIV disease. Modulation of SP activity and SP receptor may offer a novel approach to the treatment of psychiatric disorders and to the design of new anti-HIV therapy.

Abstract
Substance P (SP) acting at the NK-1 neurokinin receptor has a well-documented role in the transmission and maintenance of nociceptive information. SP is found in the majority of fibers innervating the pancreas, and it is up-regulated after pancreatic inflammation. The aim of this study was to investigate the role of the NK-1 receptors in the maintenance of pancreatic nociception. Using a newly developed rat model of acute pancreatic nociception that persists for 1 week, the NK-1 receptor expression in the spinal cord and pancreas was examined using immunohistochemistry and Western blotting procedures. The effects of a specific NK-1 antagonist, CP99,994, on the behavioral manifestations of pancreatic nociception were determined. The antagonist was administered intraperitoneally and intrathecally to differentiate peripheral and central effects. Injection of CP-100,263, the inactive enantiomer of CP-99,994 was used as a control for nonspecific effects of the antagonist. Immunohistochemistry and Western blotting analysis revealed an up-regulation of the NK-1 receptor occurs in the pancreas but not at the spinal cord level. The NK-1 antagonist was able to attenuate the nociceptive behaviors in rats with pancreatitis when applied intraperitoneally with a short duration of effectiveness. Intrathecal application of the antagonist was ineffective. These results suggest the involvement of pancreatic NK-1 receptors in the maintenance of nociception during pancreatic inflammation.

A library, evaluating a range of piperazines, piperidines and acyclic amines, as replacements for the 4-hydroxy-4-phenylpiperidine moiety in lead (1b) was prepared. These efforts identified the 4-((N)-benzimidazolone)piperidine analogue (2a) which was further optimised using classical single-compound synthesis to yield the 3-((N)-morpholino)azetidine (2j). Conformationally constrained analogues of (2j), generally offered no potency advantage in this particular series.

Abstract
Studies on tachykinin peptides and the corresponding neurokinin receptors (NKr) have increased dramatically recently due to the discovery of selective, orally-active, metabolically stable and sometimes CNS penetrating NKr antagonists. After demonstrating the potential use for NKr antagonists in animal models, some compounds have recently progressed into clinical trials and a few results have been published. NKr antagonists have demonstrated efficacy for the treatment of emesis and depression, while results in other areas have been disappointing. Nonetheless, this area is coming to the exciting time of proof of concept in humans. Demonstration of the involvement of tachykinin peptides in biological functions continues to grow, as do the potential indications for NKr antagonists. More drug candidates are undergoing clinical trials for various conditions and these results could widen the potential use for NKr antagonists.
