Pharmacological and cardiovascular perspectives on the treatment of COVID-19 with chloroquine derivatives.
Abstract The novel severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) causes coronavirus disease 2019 (COVID-19) and an ongoing severe pandemic. Curative drugs specific for COVID-19 are currently lacking. Chloroquine phosphate and its derivative hydroxychloroquine, which have been used in the treatment and prevention of malaria and autoimmune diseases for decades, were found to inhibit SARS-CoV-2 infection with high potency in vitro and have shown clinical and virologic benefits in COVID-19 patients. Therefore, chloroquine phosphate was first used in the treatment of COVID-19 in China. Later, under a lim...

Poly(ADP-ribose)polymerase is not involved in the neuroprotection exerted by azithromycin against ischemic stroke in mice.
Abstract Repurposing azithromycin has recently emerged as a promising strategy for the acute treatment of ischemic stroke. The mechanism of neuroprotection depends on the ability of this macrolide to promote polarization of microglia/macrophages towards beneficial M2 phenotypes. The immunomodulatory and anti-inflammatory effects of azithromycin, well documented in chronic inflammatory airway diseases, have been ascribed to the inhibition of the transcription factors nuclear factor (NF)-κB and activator protein (AP)-1. Since these inflammatory transcription factors are positively regulated by poly(ADP-ribose)polym...

Drug repurposing for immune modulation in acute ischemic stroke.
Abstract Innate immune cells play a dualistic role in the evolution of ischemic brain damage, with classic phenotypes promoting injury, and alternatively activated M2 microglia/macrophages or N2 neutrophils providing tissue remodelling and repair. Recently, a number of drugs commonly used for other indications (i.e., azithromycin, minocycline, bexarotene, rosiglitazone, metformin) was reported to provide neuroprotection in preclinical stroke models by promoting immune polarization towards non-inflammatory, protective phenotypes. Repurposing drugs with a well-established safety profile should allow a reduction in t...

Azithromycin protects mice against ischemic stroke injury by promoting macrophage transition towards M2 phenotype.
Abstract To develop novel and effective treatments for ischemic stroke, we investigated the neuroprotective effects of the macrolide antibiotic azithromycin in a mouse model system of transient middle cerebral artery occlusion. Intraperitoneal administration of azithromycin significantly reduced blood-brain barrier damage and cerebral infiltration of myeloid cells, including neutrophils and inflammatory macrophages. These effects resulted in a dose-dependent reduction of cerebral ischemic damage, and in a remarkable amelioration of neurological deficits up to 7days after the insult. Neuroprotection was associated ...
