摘要:
The invention provides a novel, general, and facile strategy for the creation of small molecules with high structural and stereochemical complexity. Aspects of the methods include ring system distortion reactions that are systematically applied to rapidly convert readily available natural products to structurally complex compounds with diverse molecular architectures. Through evaluation of chemical properties including fraction of sp3 carbons, ClogP, and the number of stereogenic centers, these compounds are shown to be significantly more complex and diverse than those in standard screening collections. This approach is demonstrated with natural products (gibberellic acid, adrenosterone, and quinine) from three different structural classes, and methods are described for the application of this strategy to any suitable natural product.

摘要:
The present invention relates to a process of separation of 4-aza-androst-1-ene-17-oic acid from 4-aza-androstan-17-oic acid, which brings to 4-aza-androst-1-ene-17-oic containing less than 0.05% w/w of 4-aza-androstan-17-oic acid, with high yield and productivity. In particular, the present invention relates to a process for the separation of 4-aza-androstan-17-oic acid from 4-aza-androst-1-ene-17-oic acid, comprising the steps of treating the crude 4-aza-androst-1-ene-17-oic acid with formic acid and recovering the purified 4-aza-androst-1-ene-17-oic acid containing 4-aza-androstan-17-oic acid in w/w % less than 0.05%.

摘要:
The present invention relates to new pharmaceutical uses of 4-azasteroid compounds, in particular of Finasteride/Dutasteride/Dutasteride and Dutasteride, particularly preferred of Finasteride/Dutasteride/Dutasteride, and its pharmaceutically acceptable derivatives, and combinations comprising said compounds. The invention also features generally the use of a modulator compound of neuroprotective conditions via beta subunits of shaker-type voltage-gated potassium channels and/or via members of solute carriers family 25, in particular Aralar (member 12) and adenine-nucleotide translocators 1 & 2 (member 4 & 5) and/or via a 4-nitrophenylphosphatase domain and non-neuronal SNAP25-like protein homolog 1 (NIPSNAP 1) as a neuroprotective medicament, particularly as a medicament for the prevention and/or treatment of neurological diseases such as dementia, Parkinson, Alzheimer, schizophrenia or epilepsy. The demonstrated inhibition of the MPTP appears to constitute a novel principle applicable to all pathological conditions which have underlying excitotoxic/mitochondrial mechanisms, like: amyotrophic lateral sclerosis, Alzheimer's disease, depression, epilepsy, multiple sclerosis, pain, Parkinson's disease, schizophrenia, traumatic brain and spinal chord injury, stroke and other ischemic conditions in the brain.
