Reigoselective Arylation of Thiazole Derivatives at 5-Position via Pd Catalysis under Ligand-Free Conditions
摘要:
An efficient regioselective arylation of thiazole derivatives via Pd-catalyzed C-H activation is reported. The transformation was hypothesized through a Pd(0/II) catalytic cycle in the absence of special ligand sets. This method provided an efficient process to direct arylation of thiazoles at the 5-position.
The present disclosure provides, inter alia, compounds with MASP-2 inhibitory activity, compositions of such compounds, and methods of making and using such compounds.

In one aspect, the invention provides methods for treating, inhibiting, alleviating, or preventing acute respiratory distress syndrome, pneumonia, or some other pulmonary or other manifestation of coronavirus infection, such as thrombosis, in a mammalian subject infected with coronavirus, such as SARS-CoV-2. The methods comprise the step of administering to a subject infected with coronavirus an amount of a MASP-2 inhibitory agent effective to inhibit MASP-2-dependent complement activation. In one embodiment, the MASP-2 inhibitory agent is a MASP-2 monoclonal antibody, or fragment thereof that specifically binds to a portion of SEQ ID NO:6. In one embodiment, the MASP-2 inhibitory agent is a small molecule MASP-2 inhibitory compound. In one embodiment, the subject is a human subject suffering from COVID-19-induced acute respiratory distress syndrome (ARDS) and requires supplemental oxygen prior to treatment and the MASP-2 inhibitory agent is administered in an amount sufficient to discontinue the need for supplemental oxygen.

Disclosed herein are compositions, kits and methods for determining the concentration of fluid-phase MASP-2/C1-INH complex in a biological fluid, such as a biological fluid obtained from a subject infected with SARS-CoV-2. Also disclosed are methods of using said compositions, methods and kits for detection of MASP-2/C1-INH complex to determine the status of lectin pathway activation in a mammalian subject and thereby assess the risk of a subject that is or has been infected with SARS-CoV-2 for developing COVID-19-related ARDS or other poor outcome, or determine the need for treatment or efficacy of treatment of a subject in need thereof with a complement inhibitor such as a MASP-2 inhibitory agent.
