Here, neuromodulatory effects of selective angiotensin-converting enzyme 2 (ACE2) inhibitors were investigated. Two different types of small molecule ligands for ACE2 inhibition were selected using chemical genetic approach, they were synthesized using developed chemical method and tested using presynaptic rat brain nerve terminals (synaptosomes). EBC-36032 (1 µM) increased in a dose-dependent manner spontaneous and stimulated ROS generation in nerve terminals that was of non-mitochondrial origin. ⋯ Therefore, synthesized selective ACE2 inhibitors decreased uptake of glutamate and GABA as well as exocytosis of GABA at the presynaptic level. The initial rate of glutamate uptake was the only parameter that was mitigated by both ACE2 inhibitors despite stereochemistry issues. In terms of ACE2-targeted antiviral/anti-SARS-CoV-2 and other therapies, novel ACE2 inhibitors should be checked on the subject of possible renin-angiotensin system (RAS)-independent neurological side effects.

Although coronavirus disease 2019 (COVID-19) remains a global threat, administering effective and safe vaccines is currently the most promising strategy to curb the ongoing pandemic and decrease the number of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections. However, there remains some uncertainty regarding the safety of vaccines for patients with kidney disease. ⋯ The patient's course of events of apparent IgAN exacerbation should prompt nephrologists to closely follow patients with glomerular disease after they receive a COVID-19 vaccine, especially if persistent gross hematuria occurs.
