A series of novel molecular conjugates is disclosed herein, consisting of a photosensitizer moiety chemically bonded to at least one diazirine moiety. Such conjugates react in air and/or water with non-coherent visible light to form singlet oxygen, an energetic species known to be highly toxic to abroad range of pathogens, including bacteria, fungi, microbial biofilms and viruses. Such non-specific cellular damage limits the pathogen's ability to evolve into a resistant form. The diazirine moiety of the conjugate enables the reagent to be adhesively bonded to a plethora of substrates, such as, for example, polymers, non-woven fabrics, surgical masks and gloves, hospital gowns, hospital surfaces (such as counters, mattresses, curtains) medical implants, bandages, wound dressings, or air-filters. The resulting treated substrates act as an effective pathogen-killing barrier, providing protection against the spread of such pathogens to non-infected persons.

Adducts, superstructures, and crystalline compositions prepared from a metal halide anion non-covalently bound to the outer surface of a macrocycle and methods for gold recovery are disclosed.

Compounds are of the formula (Ia), (Ib), (Ic), or are stereoisomers thereof, wherein: R1 is hydrogen, (C1-C20)alkyl; (C3-C20)alkenyl; (C3 C20)alkynyl; (C1-C6)alkyl-O—; (C3-C20)cycloalkyl; (C1 C20)haloalkyl; (C6-C20)aryl optionally substituted; (C6-C20)heteroaryl optionally substituted; R2 and R2′ are hydrogen; (C1-C20)alkyl; (C1-C6)alkyl-O—; (C1-C6)haloalkyl; halogen;cyano; and nitro; Z1 to Z4 are diradicals of formula (III) wherein Al and A2 are O—or —NR3-, wherein R3 is selected from the group consisting of hydrogen and (C1-C20)alkyl; and G is (C1-C6)alkyl; —P(═S)R5-; —P(═O)R4; P(═O)(OR4)-; —P(═O)(NR6R7)-; —S(=0)2-; S(═O)—; or —C(═O)—; and Y1 to Y4 are (C1-C8)alkyl; (C3-C7)cycloalkyl; (C6-C20)aryl optionally substituted; or (C6-C20)heteroaryl optionally substituted; and FG1 and FG2 are H, OH, or NHR8.

The present invention provides compounds of Formula (I) useful as inhibitors of PAD4, compositions thereof, and methods of treating PAD4-related disorders, (I) wherein ring A, A.sub.1, A.sub.2, A.sub.3, A.sub.4, Q, R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, and R.sub.6 along with other variables are as defined herein.

A series of new macrocycles and cage-like molecules are obtained in a high yield from a bis-(2,4-dialkoxyphenyl)arene (naphthalene, anthracene, pyrene, porphyrin, etc.) or a tris-(2,4-dialkoxyphenyl)arene (benzene, sym-tribenzobenzene) and paraformaldehyde under the catalysis of a Lewis acid. In addition, perhydroxybiphenylarenes (tetrabiphenyl trimer, naphthalene dimer, etc.) can be obtained by means of demethylation, and a variety of water-soluble derivatives can be obtained by further modification, with same exhibiting a good bond ability for guest molecules (purpurine, etc.). Moreover, the functional group introduced into the backbone enables the macrocycle to have excellent adsorption and separation capabilities and a photophysical property. The macrocyclic and cage-like molecules have commercially available raw materials, are simple to synthesize, have a high yield, and are convenient to modify, such that same have wide application prospects in gas adsorption and separation, facilitate performance improvement of luminescent materials, perform adsorption of water-soluble toxic substances, etc.
