Described herein is design, synthesis, and biological evaluation of novel series of 2-aryl-7-(3',4'-dialkoxyphenyl)-pyrazolo[1,5-a]pyrimidines acting as inhibitors of type 4 phosphodiesterase (PDE4) which is known as a good target for the treatment of asthma and COPD. For this purpose, structure optimization was conducted with the aid of structure-based drug design using the known X-ray crystallography. Also, biological effects of these compounds on the target enzyme were evaluated by using in vitro assays, leading to the potent and selective PDE-4 inhibitor (IC(50)<10nM).

In the last decades fungal infections became a major threat to human health having an unacceptably occurrence, a high rate of mortality and the number of patients at risk for these infections continue to increase every year. An effective, modern and very useful strategy in antifungal therapy is represented by the use of chimeric and hybrid drugs, most of them being with azaheterocycle skeleton. In this review, we present an overview from the last five years of the most representative achievements in the field of chimeric and hybrid diazine derivatives with antifungal properties.

Plant height is a key trait that significantly influences plant architecture, disease resistance, adaptability to mechanical cultivation, and overall economic yield. Galactinol synthase (GolS) is a crucial enzyme involved in the biosynthesis of raffinose family oligosaccharides (RFOs). It plays a significant role in carbohydrate transport and storage, combating abiotic and biotic stresses, and regulating plant growth and development.

Fitting rate constants to Hyperpolarized [1-C]Pyruvate (HP C13) MRI data is a promising approach for quantifying metabolism in vivo. Current methods typically fit each voxel of the dataset using a least-squares objective. With these methods, each voxel is considered independently, and the spatial relationships are not considered during fitting.

A series of isatin derivatives which could inhibit colorectal cancer (CRC) were synthesized. Among those compounds, 5B exhibited good inhibitory activity of CRC through the inhibition of tubulin expression, inducing apoptosis, and causing G2/M phase cell cycle arrest pathway, which suggested that 5B could be a potential tubulin inhibitor. Based on that, a novel peptide-drug conjugate (PDC), which employed the CRC cells related receptor CD44 ligand peptide A6 coupling to 5B to accomplish A6-5B.
