TYD-68
Based on 1 Customer Validation
TYD-68 is a CRBN-recruiting TYK2 PROTAC degrader with a DC50 of 0.42 nM, and displays selectivity against JAK1/JAK2-dependent signaling pathways. TYD-68 inhibits TYK2-mediated signaling, exerts therapeutic efficacy in murine psoriasis models, reduces PASI scores, downregulates TYK2 protein levels and decreases the secretion of proinflammatory cytokines, TYD-68 can be used for the study of psoriasis and other TYK2-driven autoimmune diseases.

Tyk2 0.42 nM (DC50) |
TYD-68 (compound 15t) (0.01-300 nM; 10 h) degrades TYK2 in Jurkat cells with a DC50 of 0.42 nM and a Dmax of 95%[1].
TYD-68 (1-100 nM; 10 h) selectively degrades TYK2 without affecting JAK1, JAK2, or JAK3 protein levels in Jurkat cells[1].
TYD-68 (30 nM; 4 h) shows proteome-wide degradation selectivity for TYK2 over 6873 detected proteins, with no downregulation of Ikaros or Aiolos[1].
TYD-68 (10 nM; 2-36 h) induces rapid and sustained TYK2 degradation, with significant degradation observed at 4 h and maximal degradation (~90%) at 10 h persisting up to 36 h[1].
TYD-68 (10 nM; 24 h treatment + 24 h washout) shows reversible and long-lasting TYK2 degradation[1].
TYD-68 (5 nM; 10 h) degradation of TYK2 is blocked by pre-treatment with Thalidomide (HY-14658) or Deucravacitinib (HY-117287)[1].
TYD-68 (5 nM; 10 h) degradation of TYK2 is abolished by pre-treatment with MG-132 (HY-13259), Bortezomib (HY-10227), or Pevonedistat (MLN4924) (HY-70062)[1].
TYD-68 (10 nM; 10 h) combined with Cycloheximide (CHX) (HY-12320) significantly reduces TYK2 protein stability, decreasing the half-life of TYK2[1].
TYD-68 (0.1-1000 nM; 1 h pre-incubation + 1 h stimulation) inhibits IL-12-induced STAT4 phosphorylation in CD4+ T cells of human PBMCs with an IC50 of 8.6 nM, and inhibits IFN-α-induced STAT1 phosphorylation in Jurkat cells with an IC50 of 6.7 nM[1].
