    摘要： MICROBIOLOGIC AL PROCESSES FOR HYDROXYLATING 6-SUBSTITUTED -2- ISOPROPYL-NAPHTHALENE COMPOUNDS TO THE CORRESPONDING 6-SUBSTITUTED-NAPHTHALENE PROPANOLS (E.G. 2-(6''METHOXY -2''-NAPHTYL)-1-PROPANOL; AND 2-(6''-THIOMETHYL2''-NAPHTHYL)-1-PROPANOL). THE PROCESSES ARE CHARACTERIZED BY TREATING THE 6-SUBSTITUTED-2-ISOPROPYL-NAPHTAHALENE COMPOUND WITH THE SPECIES OF THE GENUS OF FUNGI ASPERGILLUS, IDENTIFIED AS ASPERGILLUS NIGER, IN THE PRESENCE OF A NUTRIENT MEDIUM UNDER CONDITIONS CONDUCIVE TO THE MICROBIOLOGICAL AGENT. THE RESULTING PROPANOL COMPOUNDS EXHIBIT ANALGESIC, ANTI-INFLAMMATORY, AND ANTI-PYRETIC ACTIVITIES IN MAMMALS AND ACCORDINGLY HAVE UTILITY WHERE SUCH AGENTS ARE INDICATED. THE PROPANOL COMPOUNDS CAN ALSO BE CONVERTED INTO THE CORRESPONDING PROPIONIC ACID COMPOUNDS WHICH ALSO HAVE UTILITY AS ANTI-UNFLAMMATORY, ANALGESIC AND ANTI-PYRETIC AGENTS IN TREATMENT OF MAMMALS.
