NVP-AUY954 is an orally-available, benzothiazole-based, monoselective agonist of the sphingosine-1-

phosphate receptor 1 (S1P1) intended for the treatment of human autoimmune mediated inflammatory

neuropathies. Along with EC50 potency of 1.2 nM, NVP-AUY954 has at least 280-fold selectivity for S1P1

compared to the receptor's four other subtypes.

 

NVP-AUY954 induces a potent and reversible reduction of circulating lymphocytes; in combination with

Everolimus, NVP-AUY954 can prolong the survival of cardiac allografts in a rat transplantation model. NVP-

AUY954 also has been shown to activate downstream kinase cascades, increasing Erk (Tyr204) and Akt

(Ser473) phosphorylation at EC50s of 0.1 and 1.0 nM, respectively.

 

NVP-AUY954 efficacy has been correlated with an accumulation of plasmacytoid dendritic cells (pDC), which

may have therapeutic value in the treatment of multiple sclerosis.

PHA-793887 is an intravenously-administered, inhibitor of cyclin dependent kinases CDK2, CDK5, CDK7, at

IC50s of 8 nM, 5 nM, and 10 nM, respectively. [1] As a multi-CDK isoform inhibitor, it was postulated that

PHA-793887 might overcome resistance-based mechanisms and lead to enhanced tumor suppression. PHA-

793881 was found in Phase I dose-ranging studies to induce severe dose-related hepatotoxicity, thus halting

clinical studies.

 

Additionally, PHA-793887 was found to impair TLR signaling, thus suppressing cytokine production (type 1

interferon, interleukin-6, -10, -12, and TNFa), thereby increasing susceptibility of cancer patients to diseases

such as herpes viridae. [3]

 

PHA-793887 was found to be an effective tool compound for the monitoring of the E2F gene signature

pathway.

R788 is an orally-available, ATP-competitive, methylene phosphate prodrug of R406, which is a potent

inhibitor of Syk (IC50 = 41 nM). [1] In a broad panel of receptor, ion channel, and enzyme binding assays,

R406 was shown to inhibit adenosine A3 receptor (IC50 = 81 nM), adenosine transporter (IC50 = 1.8 uM), and

monoamine transporter (IC50 = 2.7 uM). Followup measurements for ligand-induced guanosine 5'-O-

(thiotriphosphate) binding to the adenosine A3 receptor showed that R406 possesses antagonistic activity

with an IC50 of 93 nM. R406 inhibits phosphorylation of Syk substrate linker for activation of T cells in mast

cells and B-cell linker protein/SLP65 in B cells. R406 does not inhibit phosphorylation of Sky tyrosine 352, but

does inhibit phosphorylation of LAT tyrosine 191. R406 also inhibits IgE- and IgG-mediated activation of Fc

receptor signaling.

 

In a large panel of diffuse large B-cell lymphoma cell lines, R406 inhibited cellular proliferation at EC50s

ranging from 0.8 to 8.1 uM.

Leukadherin-1 (LA1), a novel small molecule agonist of integrin CD11b/CD18, can increase the extent of

CD11b/CD18-dependent cell adhesion of transfected cells and of primary human and mouse neutrophils

(EC50 =4µM in vitro), which resulted in decreased chemotaxis and transendothelial migration. LA1 can also

decrease leukocyte recruitment and reduced arterial narrowing after injury in rats. Moreover, compared to a

known integrin antagonist, LA1 preserved kidney function better in a mouse model of experimental nephritis.

It inhibited leukocyte recruitment by increasing leukocyte adhesion to the inflamed endothelium, which was

reversed with a blocking antibody.
