- Polycyclic amide derivative as CDK9 inhibitor, and preparation method and application thereof
-
The invention belongs to the technical field of polycyclic amide derivatives, and particularly relates to a polycyclic amide derivative as a CDK9 inhibitor, and a preparation method and application thereof. The polycyclic amide derivative shows excellent CDK9 enzyme inhibitory activity, and can be used for preparing drugs for treating cancers, especially hematologic cancers including acute myeloid leukemia, multiple myeloma, chronic lymphocytic leukemia, follicular lymphoma and the like and solid tumors, such as acute myeloid leukemia, multiple myeloma, chronic lymphocytic leukemia and follicular lymphoma, including breast cancer, prostate cancer, ovarian cancer, hepatocellular carcinoma, pancreatic cancer, kidney cancer, stomach cancer, colorectal cancer, lung cancer and the like.

- Discovery of AZD4573, a Potent and Selective Inhibitor of CDK9 That Enables Short Duration of Target Engagement for the Treatment of Hematological Malignancies
-
A CDK9 inhibitor having short target engagement would enable a reduction of Mcl-1 activity, resulting in apoptosis in cancer cells dependent on Mcl-1 for survival. We report the optimization of a series of amidopyridines (from compound 2), focusing on properties suitable for achieving short target engagement after intravenous administration. By increasing potency and human metabolic clearance, we identified compound 24, a potent and selective CDK9 inhibitor with suitable predicted human pharmacokinetic properties to deliver transient inhibition of CDK9. Furthermore, the solubility of 24 was considered adequate to allow i.v. formulation at the anticipated effective dose. Short-term treatment with compound 24 led to a rapid dose- and time-dependent decrease of pSer2-RNAP2 and Mcl-1, resulting in cell apoptosis in multiple hematological cancer cell lines. Intermittent dosing of compound 24 demonstrated efficacy in xenograft models derived from multiple hematological tumors. Compound 24 is currently in clinical trials for the treatment of hematological malignancies.

- Synthesis of cyclic γ-amino acids for foldamers and peptide nanotubes
-
Cyclic γ-amino acids are molecular building blocks of great interest in peptide and foldamer chemistry, as they allow the preparation of new structures that are not found in Nature. In this paper, we describe the synthesis of cyclic γ-amino acids that have a cis relationship between the amino and the carboxylic acid groups. This arrangement, in most cases, induces the resulting peptides to adopt a flat conformation, which makes them appropriate for the design of foldamers that adopt β-sheet-type structures. We describe the synthesis of cyclic γ-amino acids that have a cis relationship between the amino and the carboxylic acid groups. This makes them suitable for the design of foldamers that adopt β-sheet-type structures.

- Synthesis of potent and selective inhibitors of Candida albicans N-myristoyltransferase based on the benzothiazole structure
-
Two parallel synthetic methods using solid-supported reagents were established to examine the rapid optimization of weak hit compound 1. Several compounds showed high potency in the low nanomolar range against N-myristoyltransferase. The structure-activity relationship (SAR) and antifungal activities of a series of novel 2-aminobenzothiazole N-myristoyltransferase inhibitors are presented.
