In addition to its known mechanism of actions, we performed docking prediction of this drug on the receptor-binding domain of severe acute respiratory syndrome coronavirus 2, SARS-CoV-2. We hypothesize that such interaction may possibly have contributed a role in the clinical improvements reported.Deactivation of primed SARS-CoV-2 prior to cell entry constitutes an emergency brake in COVID-19 infection if vaccine-induced antibodies fail to block recognition of the human angiotensin-converting enzyme 2 (hACE2) receptor. The timing and locus for the therapeutic intervention are dictated by the cell entry mechanism and by the selective advantage of the dominant D614G mutation.Traditionally, vertebrate models have been utilized and are viewed as more pertinent; however, we propose the application of an invertebrate model such as locusts to study human disease and sickness behavior at an early phase of research. This model has numerous benefits, namely, expense, swiftness, procedural convenience, and ethical acceptance. For example, the injection of immunogen-induced anorexia behavior in rats and locusts in vivo are analogous. Moreover, the presence of a brain barrier in locusts reveals remarkable similarities in molecular methods utilized by E. coli K1 to traverse the central nervous system of rats and locusts, consequently providing a worthwhile model to investigate pathogenesis. The presence of cytokines in these insects and presence of a brain barrier (which is physiologically relevant to human blood-brain barrier) makes it a relevant model in determining disease mechanisms and invasion of the brain by central nervous system pathogens.[This corrects the article DOI 10.1021/acsptsci.0c00003.].The eye and eyesight are exquistly designed and are precious, and yet we often take them for granted. Good vision is critical for our long-term survival and for humanity's enduring progress. Unfortunately, since ocular diseases do not culminate in life-and-death scenarios, awareness of the plight of millions of people suffering from such eye ailments is not publicized as other diseases. DMAMCL However, losing eyesight or falling victim to visual impairment is a frightening outlook for most people. Glaucoma, a collection of chronic optic neuropathies, of which the most prevalent form, primary open-angle glaucoma (POAG), is the second leading cause of irreversible blindness. POAG currently afflicts >70 million people worldwide and is an insidious, progressive, silent thief of sight that is asymptomatic. On the other hand, allergic conjunctivitis (AC), and the associated rhinitis ("hay-fever"), frequently victimizes a huge number of people worldwide, especially during seasonal changes. While not life-threatening, sufferers of AC soon learn the value of drugs to treat their signs and symptoms of AC as they desire rapid relief to overcome the ocular itching/pain, redness, and tearing AC causes. Herein, I will describe the collective efforts of many researchers whose industrious, diligent, and dedicated team work resulted in the discovery, biochemical/pharmacological characterization, development and eventual launch of drugs to treat AC (e.g., olopatadine [Patanol/Pataday/Pazeo] and emedastine [Emedine]), and for treating ocular hypertension and POAG (e.g., travoprost [Travatan ] and Simbrinza). This represents a personal perspective.We report the relaxation of methacholine-constricted airways with nebulized MIDD0301, a positive allosteric γ-aminobutyric acid type A receptor (GABAAR) modulator. The therapeutic efficacy of nebulized MIDD0301 in reducing airway resistance was investigated in spontaneous breathing mice using a whole-body plethysmograph and in unconscious mice using a forced oscillation technique. Prophylactic nebulized MIDD0301 reduced subsequent methacholine-induced bronchoconstriction in ovalbumin and house dust mite allergic asthma models and in normal mice. Nebulized MIDD0301 exhibited comparable or better therapeutic potency compared to nebulized albuterol and oral montelukast. Prophylactic nebulized MIDD0301 was also effective in reducing bronchoconstriction, comparable to nebulized albuterol or fluticasone, in a steroid resistant asthma mouse model induced by intratracheal installation of lipopolysaccharide and interferon-gamma. Oral dexamethasone was ineffective in this model. Nebulized MIDD0301 was also effective in reversing bronchospasm when dosed after methacholine challenge comparable to albuterol. Pharmacokinetic studies showed that about 0.06% of nebulized MIDD0301 entered the mouse lung when using a whole body plethysmograph and therapeutic levels were sustained in the lung for at least 25 min. Consistent with previous reports on orally dosed MIDD0301, high doses of nebulized MIDD0301 resulted in minimal brain exposure and thus no observable adverse sensorimotor or respiratory depression effects occurred. In addition, no adverse cardiovascular effects were observed following 100 mg/kg i.p. dosing. These results further demonstrate that charged imidazodiazepine MIDD0301 can selectively target lung GABAAR without adverse motor, cardiovascular, or respiratory effects and inhaled dosing is effective in reducing bronchoconstriction in allergen and infectious lung inflammation.Kidney calcification increases the risk of chronic kidney disease. However, to date, renal calcium phosphate crystallization, a main initiating and driving factor of kidney calcification, has not been explored as a drug target. Pre-clinical drug development is hampered by limited knowledge on the broad range of kidney calcification disorders, characterized by a multifactorial process of disease progression. In this work, we first established an in vitro calcification profiling platform to accelerate pre-clinical drug discovery. The image-based profiling assay allowed the rapid testing of several ionic stimuli and/or inhibitory molecules. We then leveraged a previously established library of inositol hexakisphosphate analogues to identify a renal calcium phosphate inhibitor. A lead compound showed in vitro and in vivo efficacy to prevent calcium phosphate-induced kidney damage. In conclusion, this work reports a renal calcium phosphate inhibitor that could efficiently reduce kidney damage and emphasizes the utility and translational value of the in vitro calcification platform.
