Dyclonine hydrochloride
Based on 1 publication(s) in Google Scholar
Dyclonine hydrochloride (Dyclocaine hydrochloride) is an orally active, blood-brain barrier-permeable piperidine phenylacetone small molecule commonly used as a local anesthetic. Dyclonine hydrochloride acts as a highly selective allosteric antagonist of TRPV3; it also reversibly inhibits G9a, ALDH2 and ALDH3A1, non-competitively blocks AChE. Dyclonine hydrochloride activates the Nrf2/ARE pathway, relieves the epigenetic silencing of FXN, blocks Aβ42 aggregation, and promotes remyelination and reparative polarization of microglia. Dyclonine hydrochloride alleviates pruritus via TRPV3 inhibition; it is used in studies of neurodegenerative disease models based on its AChE inhibitory, antioxidant and remyelinating effects; it sensitizes drug-resistant tumors through ALDH inhibition, and combined use with protease inhibitors induces more tumor cell apoptosis; it inhibits Candida albicans in vitro. Dyclonine hydrochloride can be used for research on multiple diseases including neurodegenerative diseases, cancer and pruritic dermatitis.

Dyclonine hydrochloride selectively inhibits purified TRPV3 channels with an IC50 of 3.2 μM; it inhibits purified ALDH2 with an IC50 of 35 μM; it also inhibits purified ALDH3A1 with an IC50 of 76 μM; and it potently and selectively inhibits purified AchE in a non-competitive manner with an IC50 of 0.18 μM[1].
Dyclonine hydrochloride inhibits the proliferation of cultured cardiomyocytes at concentrations of 1-10 μM by suppressing ALDH2; it also inhibits the proliferation of HSC4 oral squamous cell carcinoma cells cultured in vitro, and restores the sensitivity of drug-resistant HSC4 cells to Sulfasalazine (HY-14655) via ALDH inhibition[1].
Dyclonine (0.3-10 μM; 48 h) hydrochloride dose-dependently increases the FXN protein level in lymphoblasts derived from Friedreich's ataxia (FA)[2].
Dyclonine (3-30 μM; 24 h) hydrochloride dose-dependently increases the level of FXN transcripts in lymphoblasts derived from Friedreich's ataxia (FA) patients, reaching a maximum induction of approximately 3.2-fold after treatment with 30 μM for 24 h, and exhibits a stronger inductive effect in cells with longer GAA repeat sequences[2].
Dyclonine hydrochloride (5 μM; 24 h) enhances the binding of Nrf2 to the conserved ARE site in the FXN locus in lymphoblasts from FA patients[2].
Dyclonine (1-10 μM) hydrochloride dose-dependently inhibits the activity of histone methyltransferase G9a in nuclear extracts of healthy lymphoblasts; it also rescues the aconitase activity defect in lymphoblasts derived from Fanconi anemia (FA)[2].
Dyclonine (3-30 μM; with 1 mM 2-APB (HY-W009724)) hydrochloride modulates the inhibitory potency against mouse TRPV3 channels overexpressed in HEK 293T cells, and this regulatory effect relies on amino acid residues located in the channel pore region. Relative to wild-type TRPV3 with an IC50 value of 3.2 μM, L630W, N643A, I644W and L655A mutations reduce its inhibitory capacity, whereas L642A and I659A mutations strengthen its channel-blocking activity[3].
Dyclonine (15 μM) hydrochloride enhances the cytotoxic effect of 40 nM Bortezomib (HY-10227), reduces the survival rate of drug-resistant RPMI8226.BR multiple myeloma cells by approximately 80%, and induces cell apoptosis; it also enhances the cytotoxic activity of MG132 (HY-13259), inhibits the proliferation of BT549 and MDA-MB-231 breast cancer cells, and induces their apoptosis[1].
Dyclonine hydrochloride inhibits the growth of Saccharomyces cerevisiae in vitro, and exerts a synergistic effect with Calyculin A (HY-18983) to enhance this effect by targeting sterol biosynthetic enzymes including Erg2p and ERG24[1].
Dyclonine hydrochloride increases mitochondrial ATP production in cultured primary neurons and enhances their spontaneous excitatory postsynaptic current activity; it also inhibits the formation of Aβ42 oligomers in vitro[1].
Dyclonine hydrochloride potently protects fibroblasts derived from Fanconi anemia (FA) from diamide-induced oxidative stress, with an EC50 of approximately 0.2 μM[2].
Dyclonine (1.25-10 μM; 24 h) hydrochloride dose-dependently activates the Nrf2/ARE pathway in stable HeLa-ARE-luciferase cells, and luciferase activity is induced to approximately 2.5-fold after treatment with 10 μM for 24 h[2].

Dyclonine hydrochloride facilitates oligodendrogenesis, remyelination and the conversion of regenerative microglia upon oral delivery in mouse models with drug-triggered brain demyelination lesions[1].
Dyclonine (1-50 μM; intradermal injection; single administration) hydrochloride dose-dependently ameliorates TRPV3-mediated acute pruritus in mice, with the highest tested dose (50 μM) reducing the number of carvacrol (HY-N0711)-induced scratching bouts to 18.0 within 30 min[3].
Dyclonine hydrochloride reduces the number and proliferative activity of cardiomyocytes in neonatal mice after 14 days of treatment; it enhances the tumor volume reduction efficacy of Sulfasalazine in a mouse model of chemoresistant head and neck squamous cell carcinoma; and it improves the substrate oxidation capacity of whole-brain mitochondria in mice[1].
Dyclonine (1-10 mg/kg; intraperitoneal injection, oral administration; daily dosing; for 1 week) hydrochloride dose-dependently increases the levels of frataxin protein and Nrf2 target proteins, as well as aconitase activity, in the cerebellum of FA-YG8 mice[2].
Dyclonine (25 mg/kg; p.o.; daily; 4 weeks) hydrochloride restores the activity of succinate dehydrogenase in the liver, prevents the decline in balance beam performance, and increases the frataxin protein level by up to 2-fold in FA-PandKIKO mice[2].
