Manufacturing Process
1-(9H-Carbazol-4-yloxy)-3-((2-(2-methoxyphenoxy)ethyl)amino)-2-propanol
may be synthesized by the method of preparation of S-(-)-(1-carbazol-4-
yloxy)-3-[2-(2-methoxyphenoxy)]ethylaminopropan-2-ol (Patent US
4,697,022 and 4,824,963).27.5 g 4-hydroxycarbazole are dissolved in a mixture of 150 ml 1 N aqueous
sodium hydroxide solution and 70 ml dimethylsulfoxide. To this is added at
ambient temperature 13.9 g epichlorohydrin, followed by stirring for 18 hours
at ambient temperature. 280 ml water are then added thereto, followed by
stirring for 15 min and filtering off with suction. The filter residue is washed
with 0.1 N aqueous sodium hydroxide solution and water and subsequently
dissolved in methylene chloride. The methylene chloride solution is dried over
anhydrous sodium sulfate, treated with active charcoal and floridin and
evaporated. 4-(2,3-Epoxypropoxy)-carbazole is purified by recrystallising twice
from ethyl acetate. From the mother liquors there are isolated a further 4-
(2,3-epoxypropoxy)-carbazole.10 g 4-(2,3-epoxypropoxy)-carbazole are, together with 13.97 g o-methoxyphenoxyethylamine, heated under reflux in 70 ml isopropanol for 2
hours. The solvent is evaporated off and the residue is stirred for 2 hours with
a mixture of 115 ml toluene, 35 ml cyclohexane and 40 ml ethyl acetate.
After filtering off with suction, the (1-carbazol-4-yloxy)-3-[2-(2-methoxyphenoxy)]-ethylaminopropan-2-ol is recrystallised from 150 ml ethyl
acetate.
Brand name
Coreg (GlaxoSmithKline);Dilatrend.
Therapeutic Function
Beta-adrenergic blocker
General Description
Carvedilol (Coreg) is a β-blocker that hasa unique pharmacological profile. Like labetalol, it is aβ-blocker that possesses α1-blocking activity. Only the(S) enantiomer possesses the β-blocking activity, althoughboth enantiomers are blockers of the α1-receptor. Overall,its β-blocking activity is 10- to 100-fold of its α-blocking activity.
Biological Activity
Potent β -adrenoceptor and α 1 -adrenoceptor antagonist (K i values are 0.81, 0.96 and 2.2 nM for β 1 -, β 2 - and α 1 -adrenoceptors respectively) that displays antihypertensive and peripheral vasodilatory activity. Blocks cardiac inward-rectifier K + (K IR ) channels, voltage-dependent Ca 2+ channels and exhibits antioxidant properties at higher concentrations.
Biochem/physiol Actions
Cavedilol is a non-selective β-adrenergic blocker with α1 blocking activity. Carvedilol is used specifically for the treatment of heart failure and high blood pressure. It has been shown to improve left ventricular ejection fraction and may reduce mortality.
Clinical Use
Carvedilol is also unique in that it possesses antioxidantactivity and an antiproliferative effect on vascular smoothmuscle cells. It thus has a neuroprotective effect and the abilityto provide major cardiovascular organ protection. It isused in treating hypertension and congestive heart failure.
Veterinary Drugs and Treatments
Carvedilol may be useful as adjunctive therapy in the treatment
of heart failure (dilated cardiomyopathy) in dogs. There is a fair
amount of controversy at present among veterinary cardiologists as
to whether this drug will find a therapeutic niche.
in vitro
carvedilol potently inhibited fe2+-initiated lipid peroxidation in rat brain homogenate with an ic50 of 8.1 μm. in rat brain homogenate, carvedilol protected against fe2+-induced α-tocopherol depletion with an ic50 of 17.6 μm. carvedilol dose-dependently decreased the intensity of the dmpo-oh signal, with an ic50 of 25 μm [1]. carvedilol prevented vascular smooth muscle cell migration, proliferation, and neointimal formation following vascular injury. in human cultured pulmonary artery vascular smooth muscle cells, carvedilol (0.1-10 μm) concentration-dependently inhibited the mitogenesis stimulated by platelet-derived growth factor, epidermal growth factor, thrombin, and serum, with ic50 values ranging from 0.3 to 2.0 μm. carvedilol concentration-dependently inhibited vascular smooth muscle cell migration induced by platelet-derived growth factor with an ic50 value of 3 μm [3].

in the liver; the absolute bioavailability is about 25%. It
is extensively metabolised in the liver, primarily by the
cytochrome P450 isoenzymes CYP2D6 and CYP2C9,
and the metabolites are excreted mainly in the bile.
Check Digit Verification of cas no
The CAS Registry Mumber 72956-09-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,9,5 and 6 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 72956-09:
(7*7)+(6*2)+(5*9)+(4*5)+(3*6)+(2*0)+(1*9)=153
153 % 10 = 3
So 72956-09-3 is a valid CAS Registry Number.

In this work, the phase-transitioned BSA (PTB) film using the mild and fast fabrication process adhered to the capillary inner wall uniformly, and the fabricated PTB film-coated capillary column was applied to realize open tubular capillary electrochromatography (OT-CEC) enantioseparation. The enantioseparation ability of PTB film-coated capillary was evaluated with eight pairs of chiral analytes including drugs and neurotransmitters, all achieving good resolution and symmetrical peak shape. For three consecutive runs, the relative standard deviations (RSD) of migration time for intra-day, inter-day, and column-to-column repeatability were in the range of 0.3%–3.5%, 0.2%–4.9% and 2.1%–7.7%, respectively. Moreover, the PTB film-coated capillary column ran continuously over 300 times with high separation efficiency. Therefore, the coating method based on BSA self-assembly supramolecular film can be extended to the preparation of other proteinaceous capillary columns.
Drug repurposing and rediscovery: Design, synthesis and preliminary biological evaluation of 1-arylamino-3-aryloxypropan-2-ols as anti-melanoma agents

Malignant melanoma (MM) presents as the highest morbidity and mortality type in skin cancer. Herein, inspired by the previously reported anti-melanoma effect of propranolol, a widely applied β adrenergic receptor antagonist as cardiovascular drug, we set out to exploit its potential as anti-melanoma therapy based on the drug repurposing strategy. Structural optimization of propranolol yielded 5m, which exhibits dramatically improved potency on human melanoma cell growth (1.98–3.70 μM), compared to propranolol (59.5–75.8 μM). Further investigation demonstrated that 5m could inhibit colony formation of melanoma cell line (completely abolished at 2 μM for 5m, partially inhibited at 50 μM for propranolol), induce cell apoptosis and cell cycle arrest in the G2/M phase (both observed at 1 μM). Preliminary mechanism study indicated that 5m could disrupt the cellular microtubule network, which suggested tubulin as a potential target. Docking study provided a structural insight into the interaction between 5m and tubulin. In summary, our study presents a drug repurposing case that redirects a cardiovascular agent to an anti-melanoma agent.
Discovery of novel small molecule TLR4 inhibitors as potent anti-inflammatory agents

Toll-like receptor 4 (TLR4) initiates innate immune response to release inflammatory cytokines and has been pathologically linked to variety of inflammatory diseases. Recently, we found that Carvedilol, as the classic anti-heart failure and anti-inflammatory clinic drug, could inhibit the TLR4 signaling in the TLR4 overexpressed cells. Herein, we have designed and synthesized a small library of novel Carvedilol derivatives and investigated their potential inhibitory activity. The results indicate that the most potent compound 8a (SMU-XY3) could effectively inhibited TLR4 protein and the LPS triggered alkaline phosphatase signaling in HEK-Blue hTLR4 cells. It down regulated the nitric oxide (NO) in both RAW264.7 cells and BV-2 microglial cells, in addition to blocking the TNF-α signaling in ex-vivo human peripheral blood mononuclear cells (PBMC). More interestingly, 8a shows higher affinity to hyperpolarization-activated cyclic nucleotide-gated 4 (HCN4) over HCN2, which probably indicates the new application of TLR4 inhibitor 8a in heart failure, coronary heart disease, and other inflammatory diseases.
