The FT-IR, 1H NMR, electrospray mass spectrometry studies of several dipeptides containing 3-APA (3-aminophenylacetic acid) and Aib/Val/Pro, revealed that all peptides share a common structural feature, an extended backbone conformation and they form the intermolecular hydrogen bonded supramolecular β-sheet structure in the solid state. The SEM images of all peptides exhibit amyloid-like fibrils, reminiscent of many neurodegenerative diseases like Alzheimer's, Prion-protein diseases.

The invention belongs to the technical field of pyridineacetamide derivatives, and particularly relates to a pyridineacetamide derivative serving as a CDK inhibitor and a preparation method and application of the pyridine acetamide derivative. The pyridineacetamide derivative shows excellent CDK9/CDK7 enzyme inhibitory activity, and can be used for preparing drugs used 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 breast cancer, prostate cancer, ovarian cancer, hepatocellular carcinoma, pancreatic cancer, kidney cancer, stomach cancer, colorectal cancer, lung cancer and the like.

Tumour hypoxia plays an important role in tumour progression and resistance to therapy. Under hypoxia unfolded proteins accumulate in the endoplasmic reticulum (ER) and this stress is relieved through the protein kinase R-like ER kinase (PERK) signalling

With the aim of increasing the structural diversity on the early antimalarial drug plasmodione, an efficient and versatile procedure to prepare a series of biaryl- and N-arylalkylamines as plasmodione analogues is described. Using the naturally occurring and commercially available menadione as starting material, a 2-step sequence using a Kochi-Anderson reaction and subsequent Pd-catalyzed Suzuki-Miyaura coupling was developed to prepare three representative biphenyl derivatives in good yields for antimalarial evaluation. In addition, synthetic methodologies to afford 3-benzylmenadione derivatives bearing a terminal -N(Me)2 or -N(Et)2 in different positions (ortho, meta and para) on the aryl ring of the benzylic chain of plasmodione were investigated through reductive amination was used as the optimal route to prepare these protonable N-arylalkylamine privileged scaffolds. The antimalarial activities were evaluated and discussed in light of their physicochemical properties. Among the newly synthesized compounds, the para-position of the substituent remains the most favourable position on the benzyl chain and the carbamate -NHBoc was found active both in vitro (42 nM versus 29 nM for plasmodione) and in vivo in Plasmodium berghei-infected mice. The measured acido-basic features of these new molecules support the cytosol-food vacuole shuttling properties of non-protonable plasmodione derivatives essential for redox-cycling. These findings may be useful in antimalarial drug optimization.
