Abstract A series of imidazole derivatives were synthesized from two-component condensation reaction of phenylgloxal monohydrate with guanylhydrazone. They were characterized by spectroscopic and analytical techniques. The in vitro anticancer evaluation of these compounds was done on human breast cancer (MCF-7) and human liver cancer (HepG2) cell lines using the MTT assay method. Most of the newly

In some aspects, the invention relates to methods of treating conditions associated with sleep disorders, comprising administering an agent that modulates the activity of a neuropeptide receptor or a neuropeptide receptor ligand. In some aspects, the invention relates to methods of screening agents that modulate the activity of a neuropeptide receptor in an organism, optionally using cells or organisms comprising a genetic modification that affects a neuropeptide signaling pathway. In some aspects, the invention relates to methods of characterizing a condition associated with a sleep disorder comprising sequencing a nucleic acid encoding either a neuropeptide receptor or a neuropeptide receptor ligand and comparing the sequence with a reference sequence.

A self-assembled active agent may be formed by a process including covalently bonding at least a first component molecule and a second component molecule, the two component molecules displaying synergy such that the effective amount of the self-assembled active agent is lower than the sum of the effective amounts of the first component molecule and the second component molecule. The component molecules may be chosen such that the covalent bonding is reversible, for example through a hydrazone bond between an amine and an aldehyde. The active agent may thus have controllable activity such as an antimicrobial agent, a biocide, an antiviral agent, a preservative, an antifouling agent, a disinfectant, or a sensor agent, such as for a particular molecule or for pH.

been developed via tandem oxidative transformation of guanylhydrazones (in its preferentially existing azine tautomeric form) with distinct advantages such as wide substrate scope, use of substoichiometric amounts of iodine, no requirement of external oxidizing agents, base free reaction conditions, short reaction time and moderate to good yields. The role of silversalt in improving the yield and
