Here we report a new method for oxosteroid identification utilizing "tandem mass tag hydrazine" (TMTH) carbonyl-reactive derivatisation reagent. TMTH is a reagent with a chargeable tertiary amino group attached through a linker to a carbonyl-reactive hydrazine group. Thirty oxosteroids were analysed after derivatisation with TMTH by electrospray ionization massspectrometry (ESI-MS) and were found

The invention provides 3α5β–steroid compounds of general formula I. These compounds are useful in the treatment of epilepsy or comorbidities associated with epilepsy or conditions associated with convulsions, such as seizures associated with hypoxia; seizures associated with traumatic brain damage; seizures associated with intoxication; pathological changes caused by hyperexcitation; or in treatment of conditions accompanying epilepsy, such as affective disorders, depression, post-traumatic stress disorder (PTSD) and stress-related diseases, anxiety, schizophrenia and psychotic disorders, related ischemic CNS damage, neurodegenerative changes and disorders, multiple sclerosis. The compounds of general formula I also show age-specific efficacy.

Described herein are processable compositions comprising at least one moiety that is processable in its free form. Also described herein are compositions and methods for the treatment of ocular diseases or disorders including glaucoma, blepharitis, ocular inflammation, diabetic macular edema, posterior inflammation, anterior inflammation, macular degeneration (e.g., wet macular degeneration (AMD) or dry AMD), post-cataract surgery, and retinal vein occlusion. Said compositions and methods comprise steroids and prostaglandins which demonstrate anti-inflammatory activity, intraocular pressure (IOP) lowering, and/or other desirable activities. Injection of said compositions in the eye provides therapeutic benefit to patients suffering from ocular disorders.

ester groups and gave the corresponding steroidal glucosiduronic acids 12, 6 and 8. Upon treatment with diazomethane, these acids produced the equivalent methyl esters. The C-3, the C-21 and the C-3,21 glucosiduronates of 3 alpha,21-dihydroxy-5 beta-pregnan-11,20-dione were prepared by previously reported methods and converted into the corresponding C-20 semicarbazones (14, 20 and 26). With C-20 stabilized
