Abstract:
The 3-dimethyl amino substituent of the desosamine and mycaminose moieties of macrolide antibiotics are mono- and didemethylated by reaction with halogen, preferably iodine, in the presence of base at a controlled pH. The resulting compounds have antibiotic activity, and furthermore are useful as intermediates for alkylation and the like.
Abstract:
METHOD OF TREATING HYPERTENSION BY ADMINISTERING TO A HYPERTENSIVE PATIENT A THERAPWUTICALLY EFFECTIVE AMOUNT OF A COMPOUND OF THE FORMULA
O=N HO-N WHEREIN X IIS C OR N; AND R1, R2, R3 AND R4 EACH ARE HYDROGEN, ALKYL, CYCLOALKYL OR ARYL, WITH THE LIMITATION THAT R4 IS PRESENT ONLY WHEN X IS C.
Abstract:
A method for obtaining an improved aldehyde-treated erythrocyte preparation having an increased hemagglutination titer. The erythrocytes are stabilized by sequential exposure to dilute solutions of pyruvic aldehyde and formaldehyde.
Abstract:
Erythromycin E is useful as an antibiotic. The compounds is prepared by the fermentation of erythromycin with Streptomyces erythreus NRRL 3887 in suitable nutrient media.
Abstract:
3-AMINO-2-PYRIDINETHIOL HAS BEEN FOUND TO HAVE EXCELLENT ANTI-EDEMA, ANTI-PYRETIC AND ANALGESIC EFFECTS WHEN ADMINISTERED ORALLY TO WARM-BLOODED ANIMALS AT A DOSAGE OF BETWEEN 0.5 AND 50 MG./KG.
Abstract:
1,3-DIMETHYL-4,6-DI(P-SUBSTITUTED PHENYL)-6H-PYRROLO(2,3-C)PYRAZOLES AND NOVEL INTERMEDIATES USEFUL IN THEIR SYNTHESIS. THE COMPOUNDS ARE USEFUL AS ANTI-INFLAMMATORY AND ANTI-PYRETIC AGENTS.
Abstract:
Disclosed herein is an improved manometer in which the calibrated scale for reading the fluid pressure is provided on a transparent sheath rather than directly on the manometer tube, the sheath being slidably mounted on the manometer tube. This sheathing permits the zero point of the scale to be readily adjusted and includes a cylindrical portion integral with a wing, the wing carrying the scale either as a direct imprint or as an insert in the wing. An indicator for marking the meniscus level encapsulates the sheathing. The indicator is slidable on the sheathing and has a mark for establishing the pressure reading for subsequent reference.
Abstract:
Covers the use of the combination of 2-imino-5-phenyl-4oxazolidinone or a salt thereof and a potentiating agent comprising an aluminum or alkaline earth metal salt or base in treating Parkinson''s disease.
Abstract:
Covers a composition comprising the combination of 1-dopa, 2imino-5-phenyl-4-oxazolidinone or salt thereof and a third agent comprising an aluminum or alkaline earth metal salt or base and use of said composition in treating Parkinson''s disease.
Abstract:
A NEW SERIES OF PIPERDINE DERIVATIVES HAS BEEN DISCOVERED; THEY ARE COMPOUNDS CARRYING, IN THE 4-POSITION OF THE PIPERIDINE RING, A SUBSTITUTED ANILINO GROUP AND IN THE 1-POSITION, A P-FLUOROPHENYL RING SEPARATED FROM THE PIPERIDINE RING BY A CARBON CHAIN OF 4. THESE NEW COMPOUNDS AND THEIR NON-TOXIC ACID ADDITION SALTS ARE HIGHLY EFFECTIVE ANALGEICES OF LOW TOXICITY.
