Provided herein are compounds, compositions, kits, uses, and methods for assessing the viability of cells and/or quantifying the amount of live and dead cells in a mixture using differential stains. In some embodiments, the compounds are used in culture media or can function independently of fixation and/or permeabilization. In some embodiments, the compounds comprise a platinum atom. In some embodiments, the compounds comprise a nitrogen mustard moiety.

The present disclosure relates to compounds of Formula (I) or (II): (Formulae (I), (II)), and pharmaceutically acceptable salts or solvates thereof. The present disclosure also relates to pharmaceutical compositions comprising the compounds and therapeutic and diagnostic uses of the compounds and pharmaceutical compositions.

##STR00001##

The invention provides compositions of novel high penetration compositions (HPC) or high penetration prodrugs (HPP) of mustards and mustard-related compounds, which are capable of crossing biological barriers with high penetration efficiency. The HPPs are capable of being converted to parent active drugs or drug metabolites after crossing the biological barrier and thus can render treatments for the conditions that the parent drugs or metabolites can. Additionally, the HPPs are capable of reaching areas that parent drugs may not be able to access or to render a sufficient concentration at the target areas and therefore render novel treatments. The HPPs can be administered to a subject through various administration routes, e.g., locally delivered to an action site of a condition with a high concentration or systematically administered to a biological subject and enter the general circulation with a faster rate.

The present invention relates to the use of efficient phosphorous substances, in particular based on diphenylamine and heterocyclic diphenylamine derivatives as stabilizers for organic materials, in particular for plastic materials, against oxidative, thermal and/or actinic degradation. The present invention additionally relates to an organic material that has been correspondingly stabilized as described above. The invention further relates to a method of stabilizing organic materials and to specific stabilizers.

The invention provides compounds of the formula:

Novel non-nucleoside solid supports and phosphoramidite building blocks for preparation of synthetic oligonucleotides containing at least one non-nucleosidic moiety conjugated to a ligand of practical interest and synthetic processes for making the same are disclosed. Furthermore, oligomeric compounds are prepared using said solid supports and phosphoramidite building blocks, preferably followed by removal of protecting groups to provide oligonucleotides conjugated to ligands of interest.

A non-aqueous electrolyte solution for a battery contains a phosphazene compound (A) that contains at least one of a phosphazene compound represented by Formula (1) or a phosphazene compound represented by Formula (2). In Formulae (1) and (2), each of Y.sup.− and Z.sup.− independently represents an anion in which a proton is removed from an inorganic acid or an active hydrogen compound; each of twenty-four Rs independently represents a hydrocarbon group having from 1 to 10 carbon atoms; and, among the twenty-four Rs, two Rs bonded to the same nitrogen atom are optionally bonded to each other.
