Abstract: A class of 2,6-diarylpyridazinones of general structural formula I have been identified that exhibit exhibit immunosuppressant activity with human T-lymphocytes, and are useful as an immunosuppressants.

Abstract: There are disclosed certain novel compounds identified as benzo-fused lactams which promote the release of growth hormone in humans and animals. This property can be utilized to promote the growth of food animals to render the production of edible meat products more efficient, and in humans, to increase the stature of those afflicted with a lack of a normal secretion of natural growth hormone. The compounds are prepared by substitution of an amino-lactam with a substituted amide function. Growth promoting compositions containing such bezno-fused lactams as the active ingredient thereof are also disclosed.

Abstract: Novel C-3" and C-4" halogen-substituted macrolides of FK-506 type structural Formula I: ##STR1## are described. These macrolide immunosuppressants are useful in a mammalian host for the treatment of autoimmune diseases (such as juvenile-onset diabetes melitus, multiple sclerosis and rheumatoid arthritis), infectious diseases and/or the prevention of rejection of foreign organ transplants, e.g. bone marrow and heart transplants. In addition, these macrolide immunosuppressants are useful in the topical treatment of inflammatory and hyperproliferative skin diseases and cutaneous manifestations of immunologically-mediated illnesses such as: psoriasis, atopical dermatitiis, contact dermatitis and further eczematous dermatitises, seborrhoeic dermatitis, Lichen planus, Pemphigus, bullous Pemphigoid, Epidermolysis bullosa, urticaria, angioedemas, vasulitides erythemas, cutaneous eosinophilias, Lupus erythematosus or Alopecia areata.

Abstract: Novel hydroxymacrolide derivatives of the general structural Formula I: ##STR1## have been prepared from (a) suitable precursor(s) by selective reduction of the ketone at C-2.
