Реферат: A series of novel 5-(or 7-)oxo or thioxo dihydro-s-triazolo[1,5-a]pyrimidine derivatives bearing an amino, substituted amino or carboxy derivative in the 2-position, an alkyl or alkenyl substituent in the 4-position and, optionally a halogen or alkyl substituent in the 6-position. These compounds prevent broncho-spasm and are therefore useful in the treatment of asthma.
