The present disclosure novel pyrazine compounds targeting adenosine receptors (especially A1 and A2, particularly A2a). The present disclosure also relates to pharmaceutical compositions comprising one or more of the compounds as an active ingredient, and use of the compounds in the treatment of adenosine receptor (AR) associated diseases, for example cancer such as NSCLC, RCC, prostate cancer, and breast cancer.

Solid-forming local anesthetic formulations for pain control can include a lidocaine base and tetracaine base, polyvinyl alcohol, water, and an emulsifier. The formulation can be prepared to be in a semi-solid state prior to application to a skin surface, can form a soft solidified layer after application, and can provide pain relief when applied to a skin surface proximate a pain site.
