Embodiment

[0050] Reference is made to the following examples to provide those skilled in the art with a complete disclosure and description of how the described and claimed compounds, compositions, and methods were made and evaluated, and are intended to be illustrative only and not intended to be an adjudication of the inventors The scope of the invention is limited. Efforts have been made to ensure accuracy with respect to numbers (eg, amounts, temperature, etc.), but some errors and deviations should be accounted for. Unless indicated otherwise, parts are parts by weight, temperature is in °C or is at ambient temperature, and pressure is at or near atmospheric. There are many variations and combinations of reaction conditions, eg, concentrations of components, solvents required, solvent mixtures, temperatures, pressures and other reaction ranges and conditions, which can be used to optimize the process to obtain product purity and yield. Such process condition optimization requires ...

Abstract

Described herein are methods and compositions for killing or preventing the growth of microbes. It has been discovered that a class of porphyrins can kill or prevent the growth of microbes. The porphyrins can be used in a number of different applications where microbes grow.

Description

[0001] This application claims priority to US Provisional Application No. 61 / 084,403, filed July 29, 2008. This application is hereby incorporated by reference in its entirety. Background of the invention [0002] The use of antimicrobial agents to kill or prevent unwanted organisms has been extensively studied. In particular, antimicrobial agents, such as fungicides, and antiviral and antibacterial compounds have been extensively studied. While a number of antimicrobials are effective, they have drawbacks. For example, they can be highly toxic, difficult to handle and not environmentally friendly, which limits their use. Therefore, there is a need for an antimicrobial agent that can be used in many different applications, for example in aquatic applications, crop protection, treatment or prevention of diseases caused by certain microorganisms. Described herein are methods and compositions that avoid the disadvantages of current antimicrobial agents. Summary of the invent...
