摘要:
Compounds are provided having the structure ##STR1## wherein R.sup.1 is hydrogen or lower alkyl of 1-3 carbons, R.sup.2 is carboxyl, hydroxymethyl, lower alkanoyloxymethyl, or lower alkoxycarbonyl, R.sup.3 is hydrogen, lower alkyl or benzyl, and R.sup.4 and R.sup.5 are the same or different and represent hydrogen, lower alkyl, lower alkoxy, alkanoyloxy, benzyloxy, hydroxy, halogen (Cl, Br and F), nitro, and trifluoromethyl. These compounds are useful as anti-allergics when administered parenterally or by insufflation but have poor activity when administered orally.
摘要:
Compounds having the formula ##STR1## and acid-addition salts thereof, wherein R is hydrogen or alkyl of 1 to 3 carbon atoms and n is 0,1,2,3 or 4 are useful reagents for derivatizing organic compounds to permit the radioiodination of those compounds and their use as tracers in radioimmunoassays, or to permit their use as haptens.
摘要:
Intermediates are provided having the structure ##STR1## wherein X is hydrogen, lower alkyl, lower alkoxy, halogen or trifluoromethyl. These intermediates are useful in preparing pyrazolo[1,5-c]quinazoline anti-allergy compounds.
摘要:
Radiolabeled steroid derivatives having the formula ##STR1## wherein St is des-hydroxy steroid moiety of (i) a hydroxy steroid intended for radioimmunoassay or (ii) a hydroxy containing derivative of a steroid intended for radioimmunoassay, said derivative having a strong affinity for the antibodies of the steroid intended for radioimmunoassay; R is hydrogen or alkyl of 1 to 3 carbon atoms; n is 0, 1, 2, 3 or 4 and the asterisk (*) indicates tagging with a radioisotope, are useful as tracers in radioimmunoassays.
