JAK

<p>LNK01004 is a JAK inhibitor that exhibits potent inhibitory effects on JAK1 (IC50: 10 nM), JAK2 (IC50: ＜0.51 nM), and TYK2 (IC50: 1.0 nM). It can concurrently inhibit multiple cytokine-induced p-STAT signaling pathways and is applicable for research on diseases such as atopic dermatitis.</p>

JAK1/TYK2-IN-4 serves as a dual inhibitor targeting both JAK and TYK2, displaying IC50 values of 39 nM and 21 nM, respectively. It is also orally bioavailable [1].

JAK1/TYK2-IN-3, orally active, selectively inhibits TYK2 (IC50: 6 nM), JAK1 (37 nM), JAK2 (140 nM), JAK3 (362 nM), and has anti-inflammatory effects.

AZ-3 is a potent and selective JAK1 inhibitor (IC50: 34 nM).

AJI-214 functions as a dual-target inhibitor that specifically blocks Aurora kinase A and JAK2. By directly inhibiting Aurora kinase A, AJI-214 prevents mitotic progression and cell polarity in T cells while concurrently suppressing JAK2 activation to reduce STAT3 phosphorylation. This inhibition decreases the differentiation of TH1 and TH17 cells. AJI-214 is utilized in research focused on the modulation of immune responses and the prevention of graft-versus-host disease (GVHD).

JAK3-IN-11: potent oral JAK3 inhibitor (IC50=1.7 nM), noncytotoxic, >588-fold selectivity, blocks T-cell growth; useful in autoimmune research.

Tyk2-IN-10 acts as an inhibitor of the Tyrosine Kinase 2 (Tyk2)-mediated signaling pathway, which plays a role in inflammation regulation.

JAK-IN-19 inhibits JAK (pIC50: 7.2, 7.7), less so for VEGFR2 (7.0) and Aurora B (5.8).

JAK1-IN-9 (compound 23a) is a potent, selective inhibitor of JAK1, demonstrating an IC50 of 72 nM.

CEE321 is an effective pan-JAK inhibitor with an IC50 of 54 nM. It effectively inhibits biomarkers associated with atopic dermatitis.

Tyk2-IN-14, a small molecule inhibitor of TYK2, is significant in treating inflammatory diseases and conditions linked to hypersecretion of IFNa and interferons [1].

JAK2 JH2 binder-1: potent, selective, Ki=37.1 nM, potential for studying myeloproliferative neoplasms.

<p>GDC-9918 (compound GDC-9918) is an inhibitor of Janus kinases.</p>

YLIU-4-105-1 is a type II JAK2 inhibitor. Demonstrating in vivo pharmacological activity, YLIU-4-105-1 reduces splenic weight, decreases blood reticulocyte counts in a dose-dependent manner, and inhibits pSTAT5.

Cenacitinib is an effective inhibitor of Janus kinase (Janus kinase) and possesses anti-inflammatory activity.

JAK3 Covalent Inhibitor-1 is a compound characterized by its potent and selective inhibition of Janus kinase 3 (JAK3), possessing an IC50 of 11 nM and

<p>Tyk2-IN-15 (Compound 97) is a selective inhibitor of tyrosine kinase 2 (Tyk2) with an IC50 value ≤ 10 nM for Tyk2-JH2. It is utilized in the research of inflammatory and autoimmune diseases [1].</p>

JDTic, a 4-phenylpiperidine derivative distantly related to analgesics like meperidine and ketobemidone and more closely to the mu opioid antagonist alvimopan, exhibits a notably long duration of action, maintaining effects in animals for weeks following a single dose. This duration is not due to irreversible binding to the kappa opioid receptor but rather to altered activity of c-Jun N-terminal kinases. As a highly selective antagonist for the κ-opioid receptor, without influencing the μ- or δ-opioid receptors, JDTic has shown potential in animal studies for producing antidepressant and anxiolytic effects. It also demonstrates promise in treating addiction to substances such as cocaine and morphine, distinguishing itself structurally from other kappa antagonists like norbinaltorphimine.

(3R,4S)-Tofacitinib, the less active enantiomer of Tofacitinib, is a JAK3 inhibitor with an IC50 of 1 nM.

<p>Compound A8, known as JAK2-IN-9, is a selective JAK2 inhibitor with an IC50 of 5 nM.</p>
