Apoptose

<p>L5-DA, a G-quadruplex ligand, stabilizes G4s in HeLa cells, induces apoptosis, and is cytotoxic with an IC50 of 4.3 μM.</p>

DeFer-2 is a ferritin PROTAC degrader (Kd= 17.1 μM). It triggers the degradation of ferritin leading to the accumulation of free iron ions and an increase in ROS, which subsequently initiates caspase 3-GSDME mediated pyroptosis in cancer cells. DeFer-2 significantly inhibits tumor growth and extends the survival of mice with subcutaneous B16F10 tumors, and it is useful for melanoma research.

Mcl-1 Inhibitor 9 (Example 2) is a potent inhibitor of myeloid cell leukemia 1 (Mcl-1), demonstrating anti-tumor activity with an IC50 value of 0.21889 nM.

Siphonaxanthin is a carotenoid found in green algae, known for targeting the death receptor 5 (DR5) on cancer cells to induce apoptosis. In human leukemia HL-60 cells, it increases DR5 expression, reduces Bcl-2 levels, and activates caspase-3. It also inhibits fibroblast growth factor receptor-1 (FGFR-1) signaling in endothelial cells. Siphonaxanthin suppresses the proliferation, migration, and tubular formation of human umbilical vein endothelial cells (HUVECs), as well as the growth of microvessels in rat aorta rings. Additionally, it has anti-inflammatory properties by blocking the translocation of high-affinity IgE receptors (FcεRI) to lipid rafts in mast cells. Siphonaxanthin shows potential for research into diseases such as cancer, diabetic retinopathy, and rheumatoid arthritis.

CRT0066101 is a potent, orally active PKD inhibitor with IC 50 values of 1 nM, 2.5 nM, and 2 nM for PKD1, PKD2, and PKD3, respectively [1]. Additionally, it inhibits PIM2 with an IC 50 of approximately 135.7 nM and demonstrates anticancer effects [2].

GLS1 Inhibitor-6: IC50=68nM, 220x more selective for GLS2, has anti-tumor and pro-apoptosis effects.

Thalidomide-Piperazine-PEG1-NH2 is a synthetic E3 ligase ligand-linker conjugate, featuring a cereblon ligand based on Thalidomide and a single linker.

4-Hydroxyresveratrol (3,4,5,4'-Tetrahydroxystibene) is a resveratrol analog that variably induces the expression of pro-apoptotic genes such as p53 and Bax. It triggers apoptosis in SV40 virus-transformed WI38 cells (WI38VA), but not in WI38 cells. Additionally, 4-Hydroxyresveratrol significantly increases the expression of p53, GADD45, and Bax genes in WI38VA cells, while suppressing the expression of the bcl-2 gene.

AKT-IN-3: potent oral Akt inhibitor with low hERG blockage. IC50: 1.4-1.7 nM for Akt1-3. Inhibits AGC kinases like PKA, PKC.

Ferroptosis-IN-15 (compound 12) serves as an effective inhibitor of ferroptosis, exhibiting EC50 values of 0.76 μM and 0.67 μM in A375 cells and 786-O cells, respectively. It acts as a potential iron chelator and radical-scavenging antioxidant.

Cofpropamine, a caffeine derivative that inhibits polyadenylation, enhances the suppressive effects of Cyclophosphamide in animal models of rat adjuvant arthritis and mouse collagen-induced arthritis.

SMIP34 is an inhibitor of PELP1, binding to this target with a dissociation constant (Kd) of 37.4 μM. It demonstrates efficacy in inhibiting the proliferation of cancer cells and tumor progression. Specifically, SMIP34 is effective in breast cancer research, showing activity against wild-type (WT), mutant (MT) estrogen receptor-positive (ER+), and treatment-resistant (TR)-ER+ breast cancers.

Thalidomide-O-PEG4-amine TFA is a synthetic E3 ligase ligand-linker conjugate, composed of a cereblon ligand derived from Thalidomide and a single linker.

Etalocib (LY293111) sodium is an orally active leukotriene B4 (LTB4) receptor antagonist with a Ki value of 25 nM for inhibiting [3H]LTB4 binding. It exhibits an IC50 of 20 nM against LTB4-induced calcium mobilization. Additionally, Etalocib sodium can induce apoptosis.

BRD-K20733377 is a Bcl-2 inhibitor that exhibits selective cytotoxicity toward senescent cells, specifically inhibiting the activity of etoposide-induced senescent IMR-90 cells with an IC50 of 10.7 μM. Additionally, BRD-K20733377 reduces the mRNA expression of aging-related genes p16, p21, and KI67 in aged mouse models.

HDAC-IN-81 (Compound 11g) is an HDAC inhibitor capable of effectively inhibiting HDAC1 with an IC50 value of 4.5 nM. Additionally, it exhibits anticancer activity by inhibiting cell proliferation and can induce cell apoptosis (apoptosis).

LSD1-IN-21: potent LSD1 inhibitor, crosses blood-brain barrier, IC50 of 0.956 μM; lowers TNF-α, anti-cancer, anti-inflammatory.
