TGFβRI-IN-1 is an oral active and selective inhibitor of TGFβ receptor type I (TGFβRI) kinase(IC50 values of 2 nM and 7.6 μM for TGFβRI and TGFβRII, respectively ).
Link N peptide 是细胞外基质的蛋白聚糖聚集体 (proteoglycan aggregates) 的激活剂。它选择性激活 p38 丝裂原活化蛋白激酶 (MAPK) 通路,增强人椎间盘细胞中 I 型和 II 型胶原蛋白的产生。Link N peptide 有可能用于椎间盘退变类疾病的研究。
Two Rho-associated kinases (ROCK), ROCK-I and ROCK-II, act downstream of the G protein Rho to regulate cytoskeletal stability. The ROCKs play important roles in diverse cellular functions including cell adhesion and proliferation, smooth muscle contraction, and stem cell renewal. Glycyl-H-1152 is a selective and potent ROCK inhibitor (IC50 = 11.8 nM for ROCK-II). It is a glycylated isoquinoline compound derived from the therapeutically-important ROCK inhibitor HA-1077 (Fasudil) and exhibits better specificity. Thus, it poorly inhibits Ca2+/calmodulin-dependent kinase type II, protein kinase (PK) G, and Aurora A (IC50 = 2.57, 2.35, and 3.26 μM, respectively) as well as PKA or PKC (IC50 ≥ 10 μM for each). The potency of Glycyl-H-1152 is superior to that of other ROCK inhibitors, including Y-27632 (Ki = 220 nM) and HA-1077 (IC50 = 158 nM).
2'-Deoxyguanosine 5'-monophosphate (dGMP) is used as a substrate of guanylate kinases to generate dGDP, which in turn is phosphorylated to dGTP, a nucleotide precursor used in DNA synthesis. In addition, dGMP can be efficiently phosphorylated by the type I thymidylate kinase of the malarial agent P. falciparum. In humans, deficiency of mitochondrial deoxyguanosine kinase, which synthesizes dGMP from ATP and deoxyguanosine, contributes to mitochondrial DNA depletion syndrome.
Rp-8-CPT-cAMP is a structural combination of the lipophilic and non-hydrolyzable cAMP analogs, 8-CPT-cyclic AMP and Rp-cyclic AMPS .[1] It functions as a site-selective inhibitor of protein kinase A (PKA) type I and II, with preference towards site A of type I and site B of type II.2 By occupying cAMP binding sites at the regulatory subunit of PKA, Rp-8-CPT-cAMP prevents the kinase holoenzyme from dissociative activation.[2],[3]
