Synthetic Methods Driven by the Photoactivity of Electron Donor-Acceptor Complexes

The association of an electron-rich substrate with an electron-accepting molecule can generate a new molecular aggregate in the ground state, called an electron donor-acceptor (EDA) complex. Even when the two precursors do not absorb visible light, the resulting EDA complex often does. In 1952, Mulliken proposed a quantum-mechanical theory to rationalize the formation of such colored EDA complexes. However, and besides a few pioneering studies in the 20th century, it is only in the past few years that the EDA complex photochemistry has been recognized as a powerful strategy for expanding the potential of visible-light-driven radical synthetic chemistry. Here, we explain why this photochemical synthetic approach was overlooked for so long. We critically discuss the historical context, scientific reasons, serendipitous observations, and landmark discoveries that were essential for progress in the field. We also outline future directions and identify the key advances that are needed to fully exploit the potential of the EDA complex photochemistry.

Mechanism of vascular relaxation by cholinomimetic drugs with special reference to pilocarpine and arecoline

The muscarinic receptor-mediated and non-muscarinic vascular effects of cholinomimetic drugs used in glaucoma were quantified. On the isolated rat aorta, the vascular tone induced by phenylephrine is functionally antagonized by cholinomimetic drugs. Based on EC50, the relative order of potency for the endothelium-dependent vascular relaxation was acetylcholine (0.05 muM) 1 > (¡À)-methacholine (0.35 muM) 1/7 > carbachol (0.63 muM) 1/12 > (¡À)-aceclidine (1.26 muM) 1/25. The maximal effects of the four agonists varied between 82-87%. The muscarinic vascular relaxation of 0.03 muM to 100 muM pilocarpine was less than 15%. At high concentrations, pilocarpine had 1/20,000 the vascular activity of acetylcholine. Physostigmine failed to potentiate the vascular relaxation of exogenous acetylcholine, indicating the absence of acetylcholine esterase in the tissue. Arecoline, with an EC50 of 7.76 muM, was partly sensitive to the removal of the endothelium. Atropine treatment did not block the vascular effect of high concentrations of pilocarpine. Atropine, as expected, blocked the vascular effects of carbachol with KB = 3.2 nM. Pilocarpine produces vascular relaxation by its competition with spasmogens like phenylephrine, oxymetazoline, vasopressin or latanoprost. Arecoline also shares these properties with pilocarpine in the blood vessel. The molecular mechanism of the vascular effects as well as ocular clinical implications of cholinomimetic drugs is discussed.

Paneth cells during viral infection and pathogenesis

Paneth cells are major secretory cells located in the crypts of Lieberkuehn in the small intestine. Our understanding of the diverse roles that Paneth cells play in homeostasis and disease has grown substantially since their discovery over a hundred years ago. Classically, Paneth cells have been characterized as a significant source of antimicrobial peptides and proteins important in host defense and shaping the composition of the commensal microbiota. More recently, Paneth cells have been shown to supply key developmental and homeostatic signals to intestinal stem cells in the crypt base. Paneth cell dysfunction leading to dysbiosis and a compromised epithelial barrier have been implicated in the etiology of Crohn?s disease and susceptibility to enteric bacterial infection. Our understanding of the impact of Paneth cells on viral infection is incomplete. Enteric alpha-defensins, produced by Paneth cells, can directly alter viral infection. In addition, alpha-defensins and other antimicrobial Paneth cell products may modulate viral infection indirectly by impacting the microbiome. Here, we discuss recent insights into Paneth cell biology, models to study their function, and the impact, both direct and indirect, of Paneth cells on enteric viral infection.

Nickel in Photocatalysis

Robust methods to forge C-C bonds selectively are treasured by the chemical community because of the inherent value of such processes in the convergent construction of complex molecules and the notorious challenges associated with creating such linkages. The advent of cross-coupling technologies (e.g., Suzuki, Negishi, and Heck processes) has revolutionized how synthetic chemists establish C(sp2)-C(sp2) bonds. However, the mechanistic features that make these transition-metal-catalyzed processes ideal for this type of transformation are the same ones that limit their abilities to involve C(sp3)-hybridized species. In this chapter, a recently developed solution to the underlying challenge of engaging C(sp3)-hybridized nucleophiles in cross coupling is outlined: nickel/photoredox dual catalysis. By proceeding through radical intermediates, the enthalpic penalty for two-electron transmetalation can be side-stepped, and cross coupling can proceed under mild, functional-group-tolerant conditions. Several variants of this dual catalytic process are presented which, taken together, demonstrate the breadth and scope of this new cross-coupling paradigm.

Development of a high-throughput screen to identify small molecule enhancers of sarcospan for the treatment of Duchenne muscular dystrophy

Background: Duchenne muscular dystrophy (DMD) is caused by loss of sarcolemma connection to the extracellular matrix. Transgenic overexpression of the transmembrane protein sarcospan (SSPN) in the DMD mdx mouse model significantly reduces disease pathology by restoring membrane adhesion. Identifying SSPN-based therapies has the potential to benefit patients with DMD and other forms of muscular dystrophies caused by deficits in muscle cell adhesion. Methods: Standard cloning methods were used to generate C2C12 myoblasts stably transfected with a fluorescence reporter for human SSPN promoter activity. Assay development and screening were performed in a core facility using liquid handlers and imaging systems specialized for use with a 384-well microplate format. Drug-treated cells were analyzed for target gene expression using quantitative PCR and target protein expression using immunoblotting. Results: We investigated the gene expression profiles of SSPN and its associated proteins during myoblast differentiation into myotubes, revealing an increase in expression after 3 days of differentiation. We created C2C12 muscle cells expressing an EGFP reporter for SSPN promoter activity and observed a comparable increase in reporter levels during differentiation. Assay conditions for high-throughput screening were optimized for a 384-well microplate format and a high-content imager for the visualization of reporter levels. We conducted a screen of 3200 compounds and identified seven hits, which include an overrepresentation of L-type calcium channel antagonists, suggesting that SSPN gene activity is sensitive to calcium. Further validation of a select hit revealed that the calcium channel inhibitor felodipine increased SSPN transcript and protein levels in both wild-type and dystrophin-deficient myotubes, without increasing differentiation. Conclusions: We developed a stable muscle cell line containing the promoter region of the human SSPN protein fused to a fluorescent reporter. Using the reporter cells, we created and validated a scalable, cell-based assay that is able to identify compounds that increase SSPN promoter reporter, transcript, and protein levels in wild-type and dystrophin-deficient muscle cells.

High-throughput luminescent reporter of insulin secretion for discovering regulators of pancreatic Beta-cell function

Defects in insulin secretion play a central role in the pathogenesis of type 2 diabetes, yet the mechanisms driving beta-cell dysfunction remain poorly understood, and therapies to preserve glucose-dependent insulin release are inadequate. We report a luminescent insulin secretion assay that enables large-scale investigations of beta-cell function, created by inserting Gaussia luciferase into the C-peptide portion of proinsulin. Beta-cell lines expressing this construct cosecrete luciferase and insulin in close correlation, under both standard conditions or when stressed by cytokines, fatty acids, or ER toxins. We adapted the reporter for high-throughput assays and performed a 1,600-compound pilot screen, which identified several classes of drugs inhibiting secretion, as well as glucose-potentiated secretagogues that were confirmed to have activity in primary human islets. Requiring 40-fold less time and expense than the traditional ELISA, this assay may accelerate the identification of pathways governing insulin secretion and compounds that safely augment beta-cell function in diabetes.
