Abstract: A class of 2,4-; 2,3,4-; 2,4,6-; 2,3,4,5,6-substituted pyridines is provided which include novel compounds. The substitutions are achieved according to methods disclosed herein in which a metallated pyridine is reacted with an electrophile. Suitable electrophiles include CO2, SO2, dialkylcarbonates, ureas, formamides, amides, carboxylic acid esters, mono- and dihaloalkyls, halogens such as chlorine, fluorine, bromine, and iodine, metallic salts, sulfones, sulfonyls, aldehydes, ketones, anhydrides, nitriles, and electrophilic boron compounds including, but not limited to, boron trialkoxides and boron trihalides.

Abstract: The present invention provides a class of porphyrins and metal chelated porphyrins for use as inhibitors of heme iron uptake. The porphyrin/metal chelated porphyrin molecules of the invention are tetra-positively charged porphyrins based on meso-tetra(4-pyridyl)porphines. Several such agents are shown herein to cause inhibition of iron uptake in vivo and in vitro. The invention further provides therapeutic compositions including the porphyrins and/or metalloporphyrins of the invention. In addition, methods of inhibition of heme iron uptake in vivo are taught, as well as methods of treatment of diseases characterized by iron-overload. These methods include the administration of a porphyrin or metalloporphyrin in a therapeutic composition of the invention to prevent uptake of heme iron, thus preventing replenishment of a patient's iron stores.

Abstract: A series of novel positively-charged porphyrins is disclosed which exhibit a markedly increased efficiency in photosensitizing both Gram-positive and Gram-negative bacteria to the action of visible light, causing death to such bacteria when present at much lower concentrations and much shorter irradiation times than those porphyrins taught in the prior art. These porphyrins are characterized by the presence of up to four positive charges in the peripheral substituents and at least one hydrophobic tail comprising between 6 and 22 carbons inclusive, originating at one or more of the charged sites.
