Patent ID: 11850233

Abstract:
Next generation therapeutics for treatment of microorganisms (especially bacterium, fungus or certain virus) and cancer and for fluorescence diagnosis are provided. Association complex(es) effective as bactericides are formed in situ by loose interactions of molecular entities. Adjustable variable associations reduce chance bacteria develops adaptive resistance versus a single bactericide structure or method. Multifunctional variations simultaneously or sequentially attack target cells and adjust level of reactive oxygen species produced such as singlet oxygen. Claimed systems are effective bactericides in aerobic and anaerobic conditions and in absence of or presence of visible light. In presence of visible light in aerobic conditions, such are cancer treatments. Preferred are water soluble, nontoxic association complex(es). Variations can be formed by varying porphyrins and interacted metal ions, for illustration, tetrakis Ar substituted porphyrin without bound metal at core but combined with divalent metals of spatial and/or charge density characteristics similar to Zn(II) such as Co(II), Fe(II), and Mn(II).
