Synthesis of Monensin Derivatives and Their Effect on the Activity of Ricin A-Chain Immunotoxins

can be potentiated in vitro by lysosomotropic amines (e.g., NH4 Cl, chloroquine, methylamine, amantadine), ionophores (e.g., monensin, nigericin, lasalocid), or lysosomal enzyme inhibitors (e.g., leupeptin, pepstatin) (8 -13 ).

Two‐Step, One‐Pot Synthesis of Inosine, Guanosine, and 2′‐Deoxyguanosine O6‐Ethers via Intermediate O6‐(Benzotriazol‐1‐yl) Derivatives

) and Cs2 CO3 under a nitrogen atmosphere. Conversion to the O 6 ?(benzotriazol?1?yl) ethers occurs within about 10 min for inosine, and within about 60 min for guanosine and 2??deoxyguanosine. Then, for reaction with alcohols, the reaction mixture
