4‑Hydroxybenzophenone (4HBP) is a major metabolite of Benzophenone (HY-Y0546) and is orally active. 4-Hydroxybenzophenone triggers endoplasmic reticulum stress and activates the PERK-eIF2α-ATF4-CHOP and IRE1α-XBP1s pathways, and inhibits IκB translation. 4-Hydroxybenzophenone induces endoplasmic reticulum stress, unfolded protein response activation, protein homeostasis imbalance, protein aggregation, oxidative stress, ROS accumulation, mitochondrial membrane potential decrease, ATP depletion, and cytotoxicity. 4-Hydroxybenzophenone induces neural stem cell apoptosis (apoptosis) and affects neuronal differentiation. 4-Hydroxybenzophenone promotes malignant proliferation of hepatocellular carcinoma cells and xenograft tumor growth in nude mice. 4-Hydroxybenzophenone can be used in research related to neurodevelopmental toxicity and hepatocellular carcinoma.

Endoplasmic Reticulum Stress

Apoptosis

4-Hydroxybenzophenone (4HBP) (1 μM; 7 days) primarily affects NSC proliferation and induces ER stress and apoptosis in mouse NSCs; it triggers inflammatory responses and activates the NFκB signaling pathway in hippocampal NSCs^[1].

Others

4-Hydroxybenzophenone (1 μM) induces morphological changes in the endoplasmic reticulum of hippocampal NSCs^[1].
4-Hydroxybenzophenone (4HBP) (5 nM; 48 h) increases cell viability in HepG2 hepatocellular carcinoma cells, but not in normal LO2 hepatocytes^[2].
4-Hydroxybenzophenone (5 nM; 1-2 weeks) promotes colony formation in HepG2 hepatocellular carcinoma cells but not in normal LO2 hepatocytes^[2].
4-Hydroxybenzophenone (5 nM; beyond 30 passages) accelerates the proliferative capacity of HepG2 hepatocellular carcinoma cells but does not affect normal LO2 hepatocytes; at P30, it upregulates BIP and selectively activates the IRE1α-XBP1s signaling axis in HepG2 cells, induces XBP1s nuclear translocation, and increases protein aggregation^[2].
4-Hydroxybenzophenone exposure (5 nM; more than 30 passages) induces PERK reporter oligomerization and aggregate formation in HepG2 cells at P30^[2].
The 4-Hydroxybenzophenone-induced increase in cell viability, enhanced proliferation, and elevated colony formation ability in HepG2 cells are reversed by XBP1 knockdown or inhibition of the IRE1α-XBP1s pathway with MKC8866 (HY-104040)^[2].
4-Hydroxybenzophenone (4OH-BP) exhibits strong binding affinity with ESR1 and ESR2 in molecular docking simulations^[3].
4-Hydroxybenzophenone (1-1000 nM; 7 days) inhibits the proliferation of primary mouse hippocampal NSCs in vitro and reduces the viability of primary mouse hippocampal NSCs in vitro^[4].
4-Hydroxybenzophenone (1 μM; 7 days) treatment significantly upregulates the expression of Cxcl1 and other genes in primary mouse NSCs, with Cxcl1 being the most significantly upregulated gene^[4].

Cytokines and Chemokines

Apoptosis

4-Hydroxybenzophenone induces endoplasmic reticulum stress and activates the PERK signaling pathway in hippocampal neural stem cells. PERK inhibition reverses the 4-Hydroxybenzophenone-induced decrease in IκBα levels in hippocampal neural stem cells and rescues hippocampal neural stem cell apoptosis^[1].
4-Hydroxybenzophenone induces ATF4-dependent p65 transcriptional regulation; ATF4 or CHOP knockdown rescues 4-Hydroxybenzophenone-triggered hippocampal neural stem cell apoptosis; it eliminates nuclear p65 aggregation and reverses apoptosis^[1].

Cytokines & Chemokines

4-Hydroxybenzophenone (1 μM; 7 days) strongly induces Cxcl1 mRNA and protein expression in primary mouse NSCs; moreover, Cxcl1 knockdown attenuates the 4HBP-induced inhibition of proliferation and increase in apoptosis, and rescues the decrease in cell viability in primary mouse NSCs^[4].

Mitochondrial Function

4-Hydroxybenzophenone is a hydroxybenzophenone isomer that reduces mitochondrial membrane potential (MMP) with an IC₅₀ of 41.3 μM^[5].

In Vivo

ApoptosisOthers

Apoptosis

4-Hydroxybenzophenone (4HBP) (0.1-1 mg/kg/day; p.o.; throughout the 21-day gestational period) impairs hippocampal development and leads to cognitive dysfunction in offspring mice; pharmacological inhibition of PERK with GSK2606414 (HY-18072) attenuates 4HBP-induced apoptosis of NSCs in offspring, thereby improving hippocampal development and cognitive function^[1].

Others

4-Hydroxybenzophenone (4HBP) (5 nM; subcutaneous injection; 0-12 days) specifically promotes the malignant progression of HCC cells and enhances their tumorigenic potential in vivo^[2].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
