摘要:
The invention relates to a novel multi step process of making compounds of Formula I: wherein R1 is an alkoxy group and R2 is an optionally substituted, N-attached heteroaryl. The hydrogen at the 5-position can be α or β isomer, preferably α. Preferably the compound of Formula I is 17β isomer. The invention also relates to novel 3α-hydroxy-3β-substituted-17-substituted steroid compounds having GABAA receptor modulating activity, pharmaceutical compositions comprising these compounds, and the use of these compounds in a method of modulating brain excitability.
摘要:
Aqueous gel-forming compositions are prepared by reacting for 1-10 hours at 50.degree.-95.degree. C., melamine, formaldehyde and a sulfurous acid salt with the optional addition of a gel-modifying agent and/or a gelling agent which is added to the composition immediately prior to use.
摘要:
A browning composition is prepared by mixing an oil phase containing an emulsifier with an aqueous phase containing a colorant under shear conditions to form a dispersion of the aqueous phase in the oil phase.

摘要:
There is disclosed a browning composition for uncooked foods comprising a colorant and a fat or an oil. Also disclosed is a process for imparting a brown color to cooked foods by using the composition of the present invention on foods cooked, for example, in a microwave oven.
摘要:
Hydrocarbon recovery from subterranean reservoirs that are penetrated by either injector or producer wells is enhanced by selective permeability modification of the strata of the reservoir with gel-forming phenolic compositions. The injection of the phenolic composition follows a pH sequence specific to the reservoir environment which allows emplacement of the gel-forming composition the desired distance away from the wellbore and production of a uniform gel throughout the treated hydrocarbon-bearing reservoir. The permeability of a treated subterranean reservoir can be restored by treatment of the reservoir with either aqueous hypochlorite or mineral acid.
