Description

Novel biphenyl derivatives as PD-L1 inhibitors

[0001] The present invention relates to a novel compound exhibiting an inhibitory effect on the interaction between PD-1 and PD-L1, and the novel biphenyl derivative of the present invention has excellent cancer prevention and treatment through the PD-L1 inhibitory effect.

[0002] Cancer, a leading cause of death worldwide, claimed nearly 10 million lives in 2020. Cancer typically develops when normal cells transform into tumor cells, and treatment typically involves surgery, radiation therapy, or systemic therapies (chemotherapy, hormone therapy, or targeted biological therapy).

[0003] Cancer cells possess the ability to evade the immune system, allowing them to avoid attack by immune cells. Cancer cells express immunosuppressive signaling proteins, which induce immune cell dysfunction and apoptosis. One of the most well-known of these immunosuppressive signaling proteins is programmed death-ligand-1 (PD-L1).

[0004] PD-L1, also known as CD274 or B7-H1, is a transmembrane protein considered a corepressor of the immune response. It binds to programmed cell death protein-1 (PD-1) to reduce the proliferation of PD-1-positive immune cells, suppress the secretion of cytokines required for the immune response, or induce apoptosis.

[0005] PD-1 plays an important role in suppressing immune responses and promoting self-tolerance by regulating T cell activity, activating apoptosis of antigen-specific T cells, and inhibiting apoptosis of regulatory T cells. PD-L1 is known to suppress anticancer immunity by binding to PD-1 expressed on T cells, B cells, dendritic cells, and NK T cells.

[0006] On the one hand, immune checkpoint inhibitors, a form of cancer immunotherapy, are a type of drug that blocks proteins called immune checkpoints, which are expressed on certain immune cells, such as T cells, as well as cancer cells. These immune checkpoints prevent the immune response from becoming too strong, but they can also prevent T cells from killing cancer cells. Therefore, blocking these immune checkpoints can restore immune system function, making them useful in cancer treatment.

[0007] In this regard, PD-1 and PD-L1 inhibitors, representative immune checkpoint inhibitors, inhibit the binding between PD-1 and PD-L1, blocking immune tolerance and stimulating immune cell activity. Since many tumor cells highly express PD-L1, inhibiting the interaction between PD-1 and PD-L1 has been shown through animal and clinical studies to enhance T cell responses and activate the body's anti-tumor activity.

[0008] Accordingly, the present inventors have completed the present invention by developing a novel biphenyl derivative that can be usefully used for cancer prevention and treatment through an inhibitor of PD-1 or PD-L1, or inhibition of the interaction between PD-1 and PD-L1.

[0009] The present inventors studied a compound having an inhibitory effect on the interaction between PD-1 and PD-L1, synthesized a novel biphenyl derivative, identified the structure of the novel compound, and confirmed the inhibitory effect on the interaction between PD-1 and PD-L1, thereby completing the present invention.

[0010] Therefore, the present invention aims to provide a novel compound useful as a cancer prevention or treatment agent by exhibiting an effect of inhibiting the interaction between PD-1 and PD-L1.

[0379]

[0380]

[0381] 2,2'-dimethyl-[1,1'-biphenyl]-3,3'-diamine (5.0 g, 4.71 mmol) was dissolved in 50 mL of DCM, and 4-oxo-4,5,6,7-tetrahydropyrazolo[1,5-a]pyridine-2-carboxylic acid (1.7 g, 9.44 mmol), EDC (2.3 g, 11.78 mmol), and HOBt (1.6 g, 11.78 mmol) were added, and the mixture was stirred at room temperature for 12 hours.
