Provided herein are compounds and pharmaceutical compositions useful in modulating kinase activity, and related diseases. Also provided herein are methods of treating an eye disease or disorder in a subject. Also provided herein are methods of reducing intraocular pressure in a subject. Also provided herein are methods of modulating kinase activity in a cell. Also provided herein are methods of making the compounds provided herein, and compounds useful for the preparation of the compounds provided herein.

The present invention relates, in its broadest aspects, to steroidal glycosides useful in the treatment of skin disorders. Particularly, the invention relates to the use of certain steroidal glucosides, per se, or in the form aglycona, derivatives of spirostanol, of its precursor furastanol, or mixtures thereof, used in the treatment of skin disorders, for instance, psoriasis. The invention further relates to formulations containing steroidal glycosides, the process of obtaining extract from the Furcraea foetida plant, and a method of treating skin disorders.

The present invention further provides method of preparing nanocrystals of a hydrophobic therapeutic agent such as fluticasone or triamcinolone, pharmaceutical compositions (e.g., topical or intranasal compositions) thereof and methods for treating and/or preventing the signs and/or symptoms of disorders such as blepharitis, meibomian gland dysfunction or skin inflammation or a respiratory disease (e.g., asthma).
