Provided herein are compounds and their pharmaceutically acceptable salts, lipid particles comprising such compounds or pharmaceutically acceptable salts thereof and compositions of the foregoing that can be used to reduce immune intolerance in a subject, for example, to treat autoimmune disorders, or in combination with an antigenic therapy, such as a protein or gene therapy, to improve the efficacy of the antigenic therapy. The compounds have the following structural formula:

##STR00001##

wherein values for the variables (e.g., Ring A, L, R.sup.1, R.sup.2, R.sup.3, m) are as described herein.

The present invention provides a novel use of a compound having a plasminogen activator inhibitor-1 (PAI-1) inhibitory effect. Specifically, a compound having a PAI-1 inhibitory effect is used as an intranostimulator, an immune checkpoint inhibitor, an inhibitor for exacerbation of tumor cells caused by PD-L1, or an enhancer of immunotherapy for tumors, based on the inhibitory effect of the compound on expression induction of immune checkpoint molecules.

Novel tetrahydroisoquinoline derivative compounds are disclosed herein that may be used as an active ingredient for a pharmaceutical composition, and in particular, for a pharmaceutical composition useful for preventing or treating a disease or condition responsive to modulation of the contractility of the skeletal sarcomere. This may be accomplished, for example, by modulation of the troponin complex of the fast skeletal muscle sarcomere through one or more of fast skeletal myosin, actin, tropomyosin, troponin C, troponin I, and troponin T, and fragments and isoforms thereof. The tetrahydroisoquinoline derivative compounds can thus be used as an agent for preventing or treating 1) neuromuscular disorders, 2) disorders of voluntary muscle, 3) CNS disorders in which muscle weakness, atrophy, and fatigue are prominent symptoms, 4) muscle symptoms stemming from systemic disorders, and 5) dysfunctions of pelvic floor and urethral/anal sphincter muscle.
