摘要:There are provided compounds of the general formula ##SPC1## n Wherein R is a hydroxy, alkyl, acyloxy, halogen, nitro, substituted or unsubstituted amino, alkoxy, carboxy or a group derived from a carboxy group and m is 0, 1 or 2 except where m is 2, the two R groups are both hydroxy groups. n The present invention is also concerned with a process for preparing the chromonealdehyde compounds. The chromonealdehyde compounds are characterized by antiallergic properties and are therefore useful as prophylactic and therapeutic agents for allergic asthma, allergic dermatitis and other allergic diseases and also are valuable as intermediates for the synthesis of other pharmaceutical compounds having the chromone nucleus.

权利人:FLAVIN DANA; OBENLAND SIGRID
摘要:This invention provides compositions and methods of manufacturing such compositions that employ GRAS compounds which can act to promote the generation of stem, epidermal or other skin cells in the epidermis, activation of collagen synthesis, activation of hyaluronic acid synthesis, enhanced skin hydration, and dermal healing by stimulating stem cell and fibroblast migration to sites of needed repair. These compositions and methods are useful for rejuvenating the skin and for treating some skin-related aging or other dermal damaging conditions, including wrinkle reduction and treatment of minor dermal wounds.

摘要:The present invention relates to novel substituted indolo[2,3-a]quinolizines and stereoisomeric forms thereof and/or pharmaceutically acceptable salts of these compounds as well as pharmaceutical compositions containing at least one of these substituted indolo[2,3-a]quinolizines together with pharmaceutically acceptable carrier, excipient and/or diluents. Said novel substituted indolo[2,3-a]quinolizines have been identified as useful for the prophylaxis and treatment of cancer by the induction of strong mitotic delays, chromosomal misalignments and mitotic tri- and multipolarization leading to cell cycle stop and apoptosis. Furthermore a synthesis for preparation of the substituted indolo[2,3-a]quinolizines is disclosed in the present invention.
