  N6-(Arylmethyl)-N6-methyl-2,4,6-pteridinetriamines (1-15) and related N6-substituted 2,4,6-pteridinetriamines (16-20) were obtained by the condensation of 6-chloro-2,4-pteridinediamine with N-methylarylmethanamine and other selected secondary amines. The requisite N-methylarylmethanamines (21-32) were prepared by the hydrogenation over Pt/C of the corresponding arylcarboxaldehyde in the presence of methanamine. Several of the N6-(arylmethyl)-N6-methyl-2,4,6-pteridinetriamines exhibited exceptional suppressive antimalarial activity against a drug-sensitive line of Plasmodium berghei in mice. N6-Methyl-N6-(1-naphthalenylmethyl)-2,4,6-pteridinetriamine (9), the most active of these compounds, was also shown to be curative at 3.16 mg/kg in a single oral dose against P. cynomolgi in the rhesus monkey. This compound was also shown to be effective against a chloroquine-resistant line of P. berghei in the mouse but showed cross-resistance to a pyrimethamine-resistant strain. Most of the 2,4,6-pteridinetriamines showed strong antibacterial action against Streptococcus faecalis and Staphylococcus aureus.

  A series of 6-(arylthio)-2,4-pteridinediamines (IIIa) was prepared by allowing 6-chloro-2,4-pteridinediamine to react with the requisite benzenethiols in dimethyl sulfone at 190-200 degrees C. Attempts at oxidation to the corresponding sulfoxide (IIIb) or sulfone (IIIc) were unsuccessful. The compounds exhibited a spectrum of antibacterial activity similar to, but below the potency of, the related quinazolinediamines and pteridinediamines. Unlike these related types, however, they were devoid of antimalarial activity when tested against a normal drug-sensitive strain of Plasmodium berghei in mice by the parenteral route.

  6-Thioxanthopterin (13) was synthesized in four steps starting from 2-amino-4-(penthyloxy)pteridine (3) via the 8-oxide 4, its subsequent interconversion to the 6-chloro (7) and 6-thio derivative (12) and final hydrolysis of the pentyloxy group. 7-Thioisoxanthopterin (15) was derived analogously from 2-amino-4-(pentyloxy)pteridine-7(8H)-thione (14) by alkaline hydrolysis. The various 6- and 7-thiopteridines
