Specific inhibitors of puromycin-sensitive aminopeptidase with a 3-(halogenated phenyl)-2,4(1H,3H)-quinazolinedione skeleton

Specific puromycin-sensitive aminopeptidase (PSA) inhibitors with a 3-(halogenated phenyl)-2,4(1H,3H)-quinazolinedione skeleton were prepared and their structure-activity relationships were investigated. The nature (F, Cl or Br), number and position(s) of the halogen atom(s) introduced into the 3-phenyl group were concluded to be critical determinants of the inhibitory activity.

Synthesis of new substituted 6-ureidopurines and 6-ureido-9-(2,3,5-triacetyl ribofuranosyl)purines having cytokinin (plant growth promoting) activity

Substituted 6-ureidopurines 6a-j and 6-ureido-9-(2,3,5-triacetylribofuranosyl) purines 7a-j have been synthesized by condensing substituted phenyl isocyanates with adenine 3 and 2,3,5-triacetyladenosine 5 respectively in pyridine. Substituted phenyl isocyanates 2a-j are prepared from substituted anilines 1a-j in the presence of triphosgene and triethylamine in dry benzene. Compounds 6a-j and 7a-j have been evaluated for cytokinin activity on seeds of Raphanus sativus, family Brassicaceae (common name white radish) at 5 different concentrations in distilled water ranging from 0.001 to 10 mg litre-1. Compounds 6a, 7a, 7b and 7i having substitutents at 3 position of phenyl ring are found to show higher cytokinin activity than benzyladenine at all concentrations (Table II).

Polyhalogenated phenyl isocyanate synthesis with excess phosgene and either triethylamine or tetramethylurea

Two procedures are described that can be used to prepare polyhalogenated phenyl isocyanates (2,4,6-trichloro,2,3,5,6-tetrachloro, pentachloro, 2,4,6-tribromo and 2,4,6-trifluoro derivatives) from the corresponding anilines in good yields (95-99%) with sma

Method of controlling aquatic weeds

A method of controlling aquatic weeds which comprises adding to a body of water containing the aquatic weeds a substituted 1-thiadiazolyl-3-arylurea in sufficient quantity to kill the weeds.
