Imaradenant (AZD4635; HTL-1071) is a novel, potent, selective, orally bioavailable small molecule inhibitor of the adenosine A2A receptor (A2AR) (Ki = 1.7 nM) with potential anticancer immunomodulatory activity. It binds to human A2AR and exhibits > 30-fold selectivity over other adenosine receptors, making it a promising agent for cancer immunotherapy. By inhibiting A2aR signaling, AZD4635 can improve antitumor immunity and lessen the burden of tumors. In patients with solid cancers, AZD4635 is presently being investigated in a Phase 1 clinical trial both as a single treatment and in conjunction with durvalumab (anti-PD-L1 Ab). Tumors use the microenvironment's extracellular adenosine accumulation as a means of evading immune surveillance.

Enzyme Assay |
It exhibits >30-fold selectivity over other adenosine receptors and binds to human A2AR with a Ki of 1.7 nM.

Cell Assay |
Adenosine at concentrations ranging from 0.1 to 10 μM was incubated with CHO cells that were stably expressing human A2AR. The IC50 of AZD4635 for the inhibition of cAMP production was 0.79, 10.0, and 142.9 nM, respectively, in the presence of 0.1, 1, and 10 μM adenosine. AZD4635 was found to reverse suppression and restore IFNγ secretion in cells incubated with 5’-N-ethylcarboxamidoadenosine (NECA), a stable analogue of adenosine, in an ex vivo CD8+ T cell assay.

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (6.59 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.08 mg/mL (6.59 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly. View More

Calculation results
Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
