摘要:
This invention relates to processes for preparing compounds of the formula (I) and to processes for preparing certain intermediates of the formula wherein R1 is nitro, amino or protected amino; R2 is H, fluoro, chloro CF3, nitro, (C1-C4)alkyl, (C1-C4)alkoxy, amino or protected amino; and X1 is OH or a suitable leaving group, used in that process. The invention also relates novel to compounds of the formulae (II).
摘要:
The present invention relates to certain compounds of the formula (I) the racemic-enantiomeric mixtures and optical isomers of said compounds and the pharmaceutically acceptable salts or prodrugs thereof, depicted below, which are .beta.-adrenergic receptor agonists and accordingly have utility as, inter alia, hypoglycemic and antiobesity agents. More specifically, the compounds of the instant invention are selective agonists of .beta..sub.3 -adrenergic receptor. The invention also relates to methods of use for the compounds and to pharmaceutical compositions containing them. The compounds of the present invention also possess utility for increasing lean meat deposition and/or improving the lean meat to fat ratio in animals, e.g., ungulate animals, companion animals and poultry. The compounds have the formula ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, Y and Z are as defined in the specification.
摘要:
The present invention relates to compounds of the formula ##STR1## having utility as hypoglycemic and antiobesity agents, methods for their use and pharmaceutical compositions containing them. The compounds of the present invention also possess utility for increasing lean meat deposition and/or improving lean meat to fat ratio in edible animals, i.e. ungulate animals and poultry.
摘要:
A method of manufacture of thin film, field-effect transistors formed on a transparent substrate and with transparent, conductive source and drain electrodes, uses initially deposited gate electrodes as a mask in association with photolithographic processing using radiation transmitted through the substrate and electrodes to minimize parasitic capacitance between the gate and source and drain electrodes.
