Abstract: Synergistic combinations of a macrolide T-cell immunomodulator or immunosuppressant such as 33-epichloro-33-desoxyascomycin and a local anaesthetic such as lidocaine, polidocanol or prilocaine are provided, which are useful in particular in the treatment of dermatological diseases such as atopic, contact or seborrhoeic dermatitis, psoriasis, acne, rosacea, post-peel, pruritus, skin burning, or itching; and associated pain.

Abstract: Additive or synergistic combinations of a macrolide T-cell immunomodulator or immunosuppressant such as 33-epichloro-33-desoxyascomycin and a retinoid, such as etretinate, isotretinoin or tazarotene, optionally with a further pharmaceutically active agent, especially an antibacterial, are provided, which are useful in particular in the treatment of dermatological diseases such as eczema, atopic dermatitis, acne, psoriasis, skin aging, sun damage, post-peel erythema and stretch marks.

Abstract: 33-Epichloro-33-desoxyascomycin of formula I and various tautomeric or forms thereof, in crystalline form, such as Form A and Form B. Their preparation involves appropriately converting amorphous compound of formula I, or compound of formula I in other than Form A, or compound of formula I in other than Form B, respectively, from a solution thereof under crystallization-inducing conditions or conditions inducing preferential crystallization of Form A or B, respectively. Such crystals are particularly indicated for use in the preparation of topical galenical forms of the compound for pharmaceutical use, e.g. creams, emulsions and ointments.

Abstract: The compounds of formula I, ##STR1## have been found to have excellent topical activity. They are thus indicated for use in the topical treatment of inflammatory and hyperpoliferative skin diseases and of cutaneous manifestations of immunologically-induced illnesses, such as psoriasis.

Abstract: Pipecolic acid-containing peptolides wherein the peptidic backbone is of at least 9 .alpha.-amino acid residues joined together by peptide bonds, particularly the compounds of formula I ##STR1## wherein the substituents have various significances, are disclosed. They can be prepared by isolation or derivation from an appropriate microorganism strain such as S 42508/F (NRRL 15761).They have interesting pharmacological, e.g. antifungal, chemotherapeutic drug resistance reversing and to some extent immunosuppressant and antiinflammatory properties.

Abstract: New use of 11,28-dioxa-4-azatricyclo[22.3.1.0.sup.4,9 ]octacos-18-ene derivatives and pharmaceutical compositions containing themThe compounds of formula I, ##STR1## have been found to have excellent topical activity. They are thus indicated for use in the topical treatment of inflammatory and hyperpoliferative skin diseases and of cutaneous manifestations of immunologically-induced illnesses, such as psoriasis.

Abstract: The compounds of formula I ##STR1## wherein the substituents have various significances, possess pharmacological, particularly antiinflammatory and immunosuppressant activity.They can be prepared by one or more of the following process variants: reduction, deprotection, acylation, reaction with N,N'-carbonyl- or N,N'-thiocarbonyldiimidazole, halogenation, splitting off of hydrogen halide, reaction with a hydrogen carbonate, radical deoxygenation, dehydration or reaction with diazomethane of -ethane, optionally under transient protection of reactive groups which it is not desired to react.

Abstract: Benzopyrane and benzothiopyrane derivatives which possess pharmaceutical in particular anti-mycotic activity.
