Abstract: The present invention relates to novel heterocyclic compounds useful in preparing drugs for the treatment of diseases associated with various functions of the histamine 4 receptor. Specifically, these drugs are useful in the prevention or treatment of inflammatory disorder, allergy, pain, nasal polyps, rhinitis, chronic sinusitis, nasal congestion, nasal itch, asthma, chronic obstructive pulmonary disease, rheumatoid arthritis, atopic dermatitis, psoriasis, eczema, pruritus, itch skin, urticaria, idiopathic chronic urticaria, scleroderma, conjunctivitis, keratoconjunctivitis, ocular inflammation, dry eye, age-related macular degeneration, cardiac dysfunction, arrhythmia, atherosclerosis, multiple sclerosis, inflammatory bowel disease (colitis, Crohn's disease, ulcerative colitis), inflammatory pain, neuropathic pain, osteoarthritic pain, autoimmune thyroid disease, immune-mediated (also known as type I) diabetes, lupus, post-operative adhesions, vestibular disorders and cancer.

Abstract: The present invention relates to novel heterocyclic compounds useful in preparing drugs for the prevention or treatment of diseases associated with STAT3 protein. Specifically, these drugs are useful in the prevention or treatment of solid tumors, blood cancers, radiation or drug-resistant cancers, metastatic cancers, inflammatory diseases, immune system diseases, diabetes, macular degeneration, papillomavirus infections and tuberculosis.

Abstract: A heterocyclic derivative represented by formula (I), or a pharmaceutically acceptable salt or a stereoisomer thereof, which has an inhibitory effect on the activation of STAT3 protein, and is useful for the prevention or treatment of diseases associated with the activation of STAT3 protein.

Abstract: The present utility model relates to a functional mask which maintains a certain shape to improve a wearing sensation, and prevents fogging of eyeglasses and dew condensation inside the mask, particularly without pressing the nose. A functional mask according to an embodiment of the present utility model may include a mask body in which a central part corresponding to positions of an outer nose and lips protrudes and an overall shape is convex; a plurality of ventilation holes formed in the central part to facilitate the entry and exit of air; and a left outer nose support member and a right outer nose support member which are spaced apart from each other on both sides of a nose support provided at an upper position of the mask body abutting with a nose.
