PSNCBAM-1 analogs: Structural evolutions and allosteric properties at cannabinoid CB1 receptor

Allosteric modulation of the CB1Rs could represent an alternative strategy for the treatment of diseases in which these receptors are involved, without the undesirable effects associated with their orthosteric stimulation. PSNCBAM-1 is a reference diaryl urea derivative that positively affects the binding affinity of orthosteric ligands (PAM) and negatively affects the functional activity of orthosteric ligands (NAM) at CB1Rs. In this work we reported the design, synthesis and biological evaluation of three different series of compounds, derived from structural modifications of PSNCBAM-1 and its analogs reported in the recent literature. Almost all the new compounds increased the percentage of binding affinity of CP55940 at CB1Rs, showing a PAM profile. When tested alone in the [35S]GTPγS functional assay, only a few derivatives lacked detectable activity, so were tested in the same functional assay in the presence of CP55940. Among these, compounds 11 and 18 proved to be functional NAMs at CB1Rs, dampening the orthosteric agonist-induced receptor functionality by approximately 30percent. The structural features presented in this work provide new CB1R-allosteric modulators (with a profile similar to the reference compound PSNCBAM-1) and an extension of the structure-activity relationships for this type of molecule at CB1Rs.

Structure-activity relationships for 4-anilinoquinoline derivatives as inhibitors of the DNA methyltransferase enzyme DNMT1

A series of 4-anilinoquinoline derivatives related to the known inhibitor SGI-1027, containing side chains of varying pKa, were prepared by acid-catalysed coupling of the pre-formed side chains with 4-chloroquinolines. The compounds were evaluated for their ability to reduce the level of DNMT1 protein in HCT116 human colon carcinoma cells by Western blotting. With a very strongly basic N-methylpyridinium side chain, only NHCO-linked compounds were effective, whereas less strongly basic ((diaminomethylene)hydrazono)ethyl or 3-methylpyrimidine-2,4-diamine side chains allowed both NHCO- and CONH-linked compounds to show activity. In contrast, the pKa of the quinoline unit had little apparent influence on activity.

QUINOLINE DERIVATIVES FOR MODULATING DNA METHYLATION

Quinoline derivatives, particularly 4-anilinoquinoline derivatives, are provided. Such quinoline derivatives can be used for modulation of DNA methylation, such as effective inhibition of methylation of cytosine at the C-5 position, for example via selective inhibition of DNA methyltransferase DNMT1. Methods for synthesizing numerous 4-anilinoquinoline derivatives and for modulating DNA methylation are provided. Also provided are methods for formulating and administering these compounds or compositions to treat conditions such as cancer and hematological disorders.
