Aminolysis, hydrazinolysis and alkylation of 4-methoxy and 4,9-dimethoxy-6-cyano-7-thione-5-methyl-7H furo [3,2-g] [1] benzopyridine (1 a-b) yielded 7N-substituted furobenzopyridine derivatives (2 a-e or the possible isomers 3 a-e and 4 a-b), (5 a,b and 6 a,b) and the ester (8 a,b).

Aminolysis, hydrazinolysis and alkylation of 4-methoxy and 4,9-dimethoxy-6-cyano-7-thione-5-methyl-7H furo [3,2-g] [1] benzopyridine (1 a-b) yielded 7N-substituted furobenzopyridine derivatives (2 a-e or the possible isomers 3 a-e and 4 a-b), (5 a,b and 6 a,b) and the ester (8 a,b). Hydrolysis of (la) with acetic acid gave the corresponding pyridone derivatives (7). Furobenzopyridinyl-7-thioacetyl hydrazide (9 a,b) have been prepared via alkylation of furobenzopyridine thione (1 a-b) with ethyl chloroacetate followed by condensation with hydrazine hydrate. Schiff base (11) was prepared by reacting (9a) with p. N,N-dimethyl aminobenzaldehyde in boiling ethanol. Treatment of (8a) with anthranilic acid gave the corresponding 7-substituted-4H-3,1-benzoxazine-4-one (10). We found that compound (11) increased bleeding, coagulating time, the total count of white blood cells, blood glucose level (cause hyperglycemia), enzymes (GOT, GPT) activities, concentration of urea and creatinine. On the other hand it decreased red blood cells number, haemoglobin content and haematocrite value.
