Antineoplastic, Histone deacetylase inhibitor

Chidamide (Epidaza) is a histone deacetylase inhibitor (HDI) developed in China.[1] It was also known as HBI-8000.[2] It is a benzamide HDI and inhibits Class I HDAC1HDAC2HDAC3, as well as Class IIb HDAC10.[3]

Chidamide is approved by the Chinese FDA for relapsed or refractory peripheral T-cell lymphoma (PTCL), and has orphan drug status in Japan.[2][better source needed] As of April 2015 it is only approved in China.[1]

Chidamide is being researched as a treatment for pancreatic cancer.[4][5][6] However, it is not US FDA approved for the treatment of pancreatic cancer.

Chidamide (Epidaza®), a class I HDAC inhibitor, was discovered and developed by ChipScreen and approved by the CFDA in December 2014 for the treatment of recurrent of refractory peripheral T-cell lymphoma. Chidamide, also known as CS055 and HBI- 8000, is an orally bioavailable benzamide type inhibitor of HDAC isoenzymes class I 1–3, as well as class IIb 10, with potential antineoplastic activity. It selectively binds to and inhibits HDAC, leading to an increase in acetylation levels of histone protein H3.74 This agent also inhibits the expression of signaling kinases in the PI3K/ Akt and MAPK/Ras pathways and may result in cell cycle arrest and the induction of tumor cell apoptosis. Currently, phases I and II clinical trials are underway for the treatment of non-small cell lung cancer and for the treatment of breast cancer, respectively.

Chemical Synthesis

The scalable synthetic approach to chidamide very closely follows the discovery route. The sequence began with the condensation of commercial nicotinaldehyde (52) and malonic acid (53) in a mixture of pyridine and piperidine. Next, activation of acid 54 with N,N0-carbonyldiimidazole (CDI) and subsequent reaction with 4-aminomethyl benzoic acid (55) under basic conditions afforded amide 56 in 82% yield. Finally, activation of 56 with CDI prior to treatment with 4-fluorobenzene- 1,2-diamine (57) and subsequent treatment with TFA and THF yielded chidamide (VIII) in 38% overall yield from 52. However, no publication reported that mono-N-Boc-protected bis-aniline was used to approach Chidamide.
