Abstract:
A method of detecting the presence of an NBOMe in a sample which comprises of contacting the sample with an activated p-quinone such as 2,3,5,6-tetrachloro-1,4-benzoquinone (TCBQ) and an aldehyde, for example acetaldehyde, and optionally a buffer and observing a colour change, which when present, correlates with the presence of an NBOMe. The ingredients may be provided in the form of a kit which can include a colour standard or comparison chart.
Abstract:
Rhein analogues that exhibit anti-proliferative activity, particular against cancer cells, are described herein. In some embodiments, the compounds contain a flat or planar ring system. Such rings system by facilitate non-covalent binding of the compounds to the DNA complex, such as by intercalation. In some embodiment, the compounds contain a flat or planar ring system as described above and one or more substituents which are alkylating moieties, electrophilic groups or Michael acceptors or groups which contain one or more alkylating moieties, electrophilic groups and/or Michael acceptors. The compounds described herein can also contain one more functional groups to improve the solubility of the compounds.
Abstract:
This invention relates to the inhibition of histone deacetylase (HDAC) expression and enzymatic activity. The invention provides methods and reagents for inhibiting HDAC-4 and HDAC-1 by inhibiting expression at the nucleic acid level or inhibiting enzymatic activity at the protein level. Specific inhibitors are antisense oligonucleotides against HDAC-4 and HDAC-1 and trichostatin analoques .
Abstract:
Disubstituted lavendustin A analogs that are PTK inhibitors having antiproliferative activity are described. Preferred compounds of the present invention, without limitation, satisfy either Formula 1 or Formula 2. Currently preferred compounds, based on in vivo biological activity, are 4'-adamantylbenzoate-1'-N-1,4-dihydroxybenzylamine and 4'-adamantylmethylbenzoate-1'-N-1,4-dihydroxybenzylamine. The present invention also provides pharmaceutical compositions comprising effective amounts of disubstituted lavendustin A analogs. Such compositions also may comprise other active ingredients, other materials conventionally used in the formulation of pharmaceutical compositions, and mixtures thereof. The compounds and compositions of the present invention can be used for treating subjects to, for example, inhibit the proliferation of living cells in the treatment of proliferative diseases.
