Synthesis, properties and reactions of two isomeric dipyrido-1,4-dithiins of the C2h and C2v symmetry are described. Their structure determination and identification are based on spectroscopic methods (1H and 13C NMR, HETCOR, gHMBC and MS), physical properties (mp and Rf), the 1,4-dithiin ring opening reactions and finally X-Ray analysis. A very unusual type of the Smiles rearrangement (S→S, the pyridyl group migrates from one sulfur atom to another) during the 1,4-dithiin ring opening with sodium methanethiolate enabling isomerization of dithiin with the C2h symmetry to dithiin with the C2v symmetry is found.

The present invention relates to a method of treating cancer in a mammal and to pharmaceutical combinations useful in such treatment. In particular, the method relates to a cancer treatment method that includes administering an erb family inhibitor and a PI3K and/or Akt inhibitor to a mammal suffering from a cancer.

A series of 9-(hydroxyalkyl)-3-deazaadenines, which are analogues of the carbocyclic derivative of 3-deazaadenosine (3-deaza-C-Adpo), were synthesized. The analogues were tested as inhibitors of bovine liver S-adenosyl-L-homocysteine (AdoHcy) hydrolase (EC 3.3.1.1) and as inhibitors of vaccinia virus (WR) replication in clone 929 mouse L cells and the results were compared to those observed for the parent compound, 3-deaza-C-Ado. 4-Amino-1-(2,3-dihydroxy-1-propyl)imidazo[4,5-c]pyridine (14), the analogue which included the 1'-, 2'- and 3'-carbons of 3-deaza-C-Ado, was the most active inhibitor toward purified AdoHcy hydrolase. The inhibitory effect of 14 (K(i) = 768 nM) on AdoHcy hydrolase was significantly less than that observed for 3-deaza-C-Ado (K(i) = 4 nM). Analogue 14 also exhibited inhibitory activity against vaccinia virus replication, but the activity was less than that observed with 3-deaza-C-Ado. 4-Amino-1-(4-hydroxy-1-butyl)imidazo[4,5-c]pyridine (15) showed little or no inhibitory activity toward AdoHcY hydrolase, but it did exhibit antiviral effects comparable to 14. These results suggest that 3-deaza-C-Ado and analogue 14 may be producing their antiviral effects by altering a critical viral methylation (e.g., methylation of the 5'-cap of viral mRNA), whereas analogue 15 may be acting through an alternative mechanism.
