In order to obtain more potent growth hormone secretagogues, a comparison of ipamorelin and NN703 suggested the addition of a polar group at the C-terminus of NN703. A study was conducted using constrained amines for this purpose. Here, substituted 4-piperidinylamino- and 4-dimethylaminopiperidino-substituents were found to give the most active compounds A replacement of the 4-dimethylaminopiperidino-substituent with 4-hydroxypiperidino resulted in a series of compounds, which showed in vitro activity with EC50 values in the low nanomolar range, and favorable kinetic properties, such as 40% oral bioavailability. The most promising compound was also tested in a swine in vivo model, resulting in a growth hormone level with a Cmax of over 40 ng mL-1.

Two series of pyrazolo[3,4-d]pyrimidine analogs I (R = Ph, substituted Ph; R1 = Me; R = Ph, R1 = Et, Pr, Bu, Ph; R = 3-ClC6H4, R1 = Et, Pr, Bu) of 1-methylisoguanosine have been synthesized. All I were tested for A1 adenosine receptor affinity by using a (R)-{3H}-N6-(phenylisopropyl)adenosine binding assay. The 3-chlorophenyl group showed the greatest activity in the N1-position and the Bu group produced the greatest activity in the N5-position. Combination of the best substituent in each of these positions enhanced the overall activity. The most potent compound was I (R = 3-C6H4Cl, R1 = Bu) (II) with an IC50 of 6.4 × 10-6M. Selectivity at the receptor subclasses was examined by performing an A2 adenosine receptor affinity assay with [3H]CGS 21680. This series of compounds were slightly less potent at A2 receptors.

In addition, there is a lot of other information about this compound (cas:254905-58-3) here.

Exploration of small selective ligands for the nicotinic acetylcholine receptors (nAChRs) based on acetylcholine (ACh) has led to the development of potent agonists with clear preference for the α4β2 nAChR, the most prevalent nAChR subtype in the central nervous system. In this work the authors present the continuation of these efforts aimed at increasing this subtype selectivity by introduction of conformational restriction in the carbamoylcholine homolog, 3-(dimethylaminobutyl) dimethylcarbamate (DMABC). The results highlight the importance of the N-carbamoyl substitution in α4β2-subtype selectivity. Moreover, the authors have confirmed the non-linear conformation of DMABC bound to nAChRs suggested by recent crystal structures of the compound in complex with the Lymnaea stagnalis ACh binding protein.

Keywords: trisubstituted pyridine preparation bioavailability WNT signaling inhibitor antitumor. We’ll tell you more about this compound (cas:254905-58-3).

WNT signaling is frequently deregulated in malignancy, particularly in colon cancer, and plays a key role in the generation and maintenance of cancer stem cells. The authors report the discovery and optimization of a 3,4,5-trisubstituted pyridine, 1-(3,5-Dichloropyridin-4-yl)piperidine-4-carboxamide (9), using a high-throughput cell-based reporter assay of WNT pathway activity. The authors demonstrate a twisted conformation about the pyridine-piperidine bond of (9) by small-mol. x-ray crystallog. Medicinal chem. optimization to maintain this twisted conformation, cognisant of physicochem. properties likely to maintain good cell permeability, led to 8-[3-Chloro-5-[4-(1-methyl-1H-pyrazol-4-yl)phenyl]pyridin-4-yl]-2,8-diazaspiro[4,5]decan-1-one (74) (CCT251545), a potent small-mol. inhibitor of WNT signaling with good oral pharmacokinetics. The authors demonstrate inhibition of WNT pathway activity in a solid human tumor xenograft model with evidence for tumor growth inhibition following oral dosing. This work provides a successful example of hypothesis-driven medicinal chem. optimization from a singleton hit against a cell-based pathway assay without knowledge of the biochem. target.
