Development of small-molecule modulators of the transcription factor brachyury

Written in collaboration with Tigran M. Abramyan (Alexander Tropha’s lab at UNC Chapel Hill) In my previous open lab notebook entry I described the in silico approach using the program SparkTM to grow fragments found to co-crystallize within binding site A of the transcription factor brachyury to compounds with hopefully higher binding potency. The overall aim Read More …

Synthesis and biological evaluation of H-8 analogues as PKN3 inhibitors

The protein kinase N3 (PKN3) represents one of the understudied kinases in the human kinome and therefore one of the kinases SGC-UNC wants to target. As part of the UNC-SOLAR program, a summer program for students, Guillermo Correa Otero was working with me in the lab for 9 weeks. Under the supervision of David Drewry, Read More …

Growing co-crystallized fragments to ligands of the transcription factor brachyury (T)

In order to develop ligands addressing different possible binding sites of the transcription factor brachyury, fragments co-crystallized with this protein should be developed into ligands by using the program SparkTM (Cresset®). Brachyury (T, TBXT) is an essential regulator of the notochord development. Brachyury is primarily expressed in the embryo but not in the majority of normal Read More …

Selective CDKL2 inhibitors – molecular modeling

At SGC we are interested in developing protein kinase inhibitors with a high selectivity towards other protein kinases. Based on lead compounds from the literature and our group new and selective CDKL2 inhibitors should be designed, synthesized and tested. Carla Alamillo, a former member of our group, worked on this topic and mentioned in her Read More …
