The transcriptional activation of HoxD genes during mammalian limb development involves dynamic interactions with two topologically associating domains (TADs) flanking the HoxD cluster. In particular, the activation of the most posterior HoxD genes in developing digits is controlled by regulatory elements located in the centromeric TAD (C-DOM) through long-range contacts.

Herpesviruses can infect a wide range of animal species. Herpes simplex virus 1 (HSV-1) is one of the eight herpesviruses that can infect humans and is prevalent worldwide. Herpesviruses have evolved multiple ways to adapt the infected cells to their needs, but knowledge about these transcriptional and post-transcriptional modifications is sparse.

The impact of signal-dependent transcription factors, such as glucocorticoid receptor and nuclear factor kappa-b, on the three-dimensional organization of chromatin remains a topic of discussion. The possible scenarios range from remodeling of higher order chromatin architecture by activated transcription factors to recruitment of activated transcription factors to pre-established long-range interactions.

The physiological role of lectins in a plant is still not well understood. The overabundant presence of lectins in plant seeds and storage tissues indicated their role in plant development. Plant lectins shows a broad range of activities like antibacterial, antifungal, insecticidal, anticancerous, antileishmanial, antiviral, and anticoagulants. In this review, we aim to highlight the plant lectins classification and their application in various biological aspects.

Twenty-five new hydroxy- and methoxy-substituted 4,6-diarylpyrimidin-2(1H)-ol (20–34) and 4,6-diarylpyrimidine-2(1H)-thiol derivatives (35–44) were synthesized from the reaction of the corresponding 1,3-diaryl-2-propene-1- one compounds (1–19) with urea or thiourea using the solid-phase microwave method. All the new synthetic compounds (20–44) were evaluated with regard to their α-glucosidase activity. However, only compounds 22–25, 27, 31, 34, 35, 37, and 40 exhibited a greater inhibitory effect than standard acarbose. The IC50 values of the active compounds ranged between 2.36 and 13.
