Title
(EN) SYSTEMS AND METHODS FOR STEROIDAL GELS
(FR) SYSTÈMES ET PROCÉDÉS POUR DES GELS STÉROÏDIENS
Abstract
(EN)
The present invention generally relates to compositions, such as gels comprising steroids. In certain aspects, the steroids are modified such that they can form gels, e.g., when complexed to metal ions. In some cases, the steroids form fibers, such as nanofibers, within the gel. For instance, in one set of embodiments, a steroid may be relatively hydrophobic, and/or modified to include a phosphate moiety that is able to complex to metal ions to form the gel. In some cases, such gels may be administered to a subject, e.g., through injection. Other aspects of the invention are generally directed to methods of making or using such gels, kits comprising such gels, or the like.
(FR)
La présente invention concerne de façon générale des compositions, telles que des gels comprenant des stéroïdes. Dans certains aspects, les stéroïdes sont modifiés de façon à ce qu'ils puissent former des gels, par exemple lorsqu'ils sont complexés à des ions métalliques. Dans certains cas, les stéroïdes forment des fibres, telles que des nanofibres, à l'intérieur du gel. Par exemple, dans un ensemble de modes de réalisation, un stéroïde peut être relativement hydrophobe et/ou modifié pour inclure un groupe phosphate qui est capable de se complexer avec des ions métalliques pour former le gel. Dans certains cas, de tels gels peuvent être administrés à un patient, par exemple par injection. D'autres aspects de la présente invention concernent de manière générale des procédés de fabrication ou des méthodes d'utilisation de tels systèmes, des kits comprenant de tels systèmes, ou autres.
