Glaucoma Drug
Bimatoprost is a synthetic amide F2α derivative ,it can selectively simulate the effect forefront amines produced by the body, which make aqueous humor production rate increase aqueous outflow resistance is reduced, by increasing the amount of aqueous outflow of the uveoscleral and trabecular Netcom channel to reduce intraocular pressure (IOP),it is considered to be the most effective hypotensive drug of topical ocular anti-glaucoma drugs,it is suitable for the treatment of open-angle glaucoma (POAG) or invalid elevated intraocular other ocular hypotensive medications compression syndrome (OHT) patients.
Side effects
1. to deepen the color of the iris, blepharitis, eye irritation and pain; black eyelashes thicker growth; conjunctival hyperemia, temporarily punctate corneal epithelial erosion, eyelid edema and erythema; rash.
2. rare respiratory disorders, asthma exacerbations, iritis, uveitis, eyelid skin darkening.
3. very rare chest pain, pharyngitis.
4. eye itching, allergic conjunctivitis, cataract, conjunctival edema, secretions, photophobia, superficial punctate keratitis, headache, high blood pressure.
Glaucoma commonly used drugs
1. prostaglandin derivatives such as latanoprost (Xalatan), bimatoprost (trade name Lumigan) and travoprost (Travatan) can increase outflow of aqueous humor uveoscleral . Bimatoprost also increases trabecular outflow.
2. topical β-adrenergic such as timolol, levobunolol (Betagan), and betaxolol can decrease receptor antagonist of aqueous humor production of ciliary body .
3. Alpha2-adrenergic agonists such as brimonidine (Alphagan) with dual working mechanism, can reduce aqueous humor production and increase trabecular outflow.
4. one case of the selective reduction similar to epinephrine and dipivefrin (Propine) increase outflow of aqueous humor through trabecular meshwork and possibly through uveoscleral outflow pathway, probably by a β2-agonist action.
5. miotic agents (parasympathomimetics), if ciliary muscle contraction Roca works, it can tighten the trabecular and allow increaseing outflow of aqueous humor. Ecothiopate is used for chronic glaucoma.
6. dorzolamide (Trusopt), brinzolamide (Azopt), by inhibiting carbonic anhydrase acetazolamide of ciliary body, reduce aqueous humor secretion of carbonic anhydrase inhibitors.
7. Physostigmine is also used to treat glaucoma and delayed gastric emptying.

Bimatoprost - timolol maleate compound eye drops
In July 2006 , bimatoprost-timolol maleate compound eye drops developed by the United States company obtained approval from the European drug regulatory authority for reducing intraocular pressure or ocular hypertension of open-anglepatients glaucoma patients who do not respond adequately to the β-blockers or prostaglandin like treatment .
The compound eye drops containing 0.03% bimatoprost and 0.5% timolol maleate, once a day administration is able to provide clinically effective pressure control, the effect is better than single Bima latanoprost or timolol maleate.
Clinical trials prove that the drug has an excellent tolerability, including the incidence of ocular hyperemia40% lower compared to single bimatoprost .
Description
Bimatoprost was first introduced in the US and Brazil as Lumigan?, an ophthalmic
solution (0.03%) for the reduction of elevated intraocular pressure (IOP) in patients with
open-angle glaucoma or ocular hypertension, a proven risk of glaucomatous visual field
loss. Bitamoprost is a new agent belonging to the PGF2α analog class of prostamides
launched in this indication after latanoprost, the most efficaceous topical medication
currently available. This synthetic fatty acid amide can be prepared by esterification of 17-
phenyl-18,19,20-trinorprostaglandin F2α followed by ethylamidation. Bimatoprost, as related
prostamides, is devoid of typical activities associated with PGF2,, analogs; it exhibits a
unique pharmacological profile in contracting the feline iris sphincter with an EC50 of 34 nM
without interacting with any known prostanoid receptors. Thus it mimics the action of
endogenous prostamides on specific receptors that lower IOP by increasing aqueous
humor outflow through both pressure-insensitive and pressure-sensitive pathways without
reducing humor formation. In a 3-month controlled clinical trial of efficacy and safety in patients with elevated IOP, bimatoprost demonstrated lower mean intraocular pressures at
every time point throughout the study, as well as a good tolerance and systemic safety
profile compared to latanoprost.

Uses
Different sources of media describe the Uses of 155206-00-1 differently. You can refer to the following data:
1. Antiglaucoma. Synthetic prostamide; structurally related to prostaglandin F2a.
2. Bimatoprost is a prostaglandin analog used topically (as eye drops) to control the progression of glaucoma and in the management of ocular hypertension. It reduces intraocular pressure (IOP) by increasing the outflow of aqueous fluid from the eyes. It ha
3. Bimatoprost is an antiglaucoma agent. Bimatoprost is an synthetic prostamide; structurally related to prostaglandin F2α.
4. 17-phenyl trinor Prostaglandin F2α ethyl amide (17-phenyl trinor PGF2α ethyl amide) is an F-series PG analog which has been approved for use as an ocular hypotensive drug. Investigations in our lab have shown that 17-phenyl trinor PGF2α ethyl amide is converted by an amidase enzymatic activity in the bovine and human cornea to yield the corresponding free acid, with a conversion rate of about 40 μg/g corneal tissue/24 hours. The free acid, 17-phenyl trinor PGF2α, is a potent FP receptor agonist. In human and animal models of glaucoma, FP receptor agonist activity corresponds very closely with intraocular hypotensive activity.[Cayman Chemical]

General Description
Bimatoprost (Lumigan) is supplied as a sterile 0.03%ophthalmic solution in 2.5- and 5.0-mL sizes. The recommendeddosage of bimatoprost is limited to one drop intothe affected eye once daily in the evening. Increased usagemay decrease its beneficial effect. If used concurrently withother IOP-lowering drugs, a waiting period of 5 minutesshould separate administrations.
Check Digit Verification of cas no
The CAS Registry Mumber 155206-00-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,2,0 and 6 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 155206-00:
(8*1)+(7*5)+(6*5)+(5*2)+(4*0)+(3*6)+(2*0)+(1*0)=101
101 % 10 = 1
So 155206-00-1 is a valid CAS Registry Number.

A new synthetic approach to prostaglandin analogues: Synthesis of bimatoprost via lipase enzymatic catalysis
Kamidi, Vijendhar,Kale, Pooja,Boodida, Sathyanarayana
, p. 2767 - 2770 (2017)
A simple, convenient and efficient synthetic approach for the synthesis of (15S) bimatoprost (4) via lipase enzyme mediated stereo selective reduction from chiral precursor Corey lactone diol as substrate was described. Swern oxidation, lipase enzymatic reduction and Wittig reaction conditions are used as key steps for the synthesis of bimatoprost. This method was found to be an efficient with considerable yield, cost effective and minimized the synthetic steps compared to reported procedures.
Access to a Key Building Block for the Prostaglandin Family via Stereocontrolled Organocatalytic Baeyer–Villiger Oxidation
Zhu, Kejie,Hu, Sha,Liu, Minjie,Peng, Haihui,Chen, Fen-Er
, p. 9923 - 9927 (2019/05/16)
A new protocol for the construction of a crucial bicyclic lactone of prostaglandins using a stereocontrolled organocatalytic Baeyer–Villiger (B-V) oxidation was developed. The key B-V oxidation of a racemic cyclobutanone derivative with aqueous hydrogen peroxide has enabled an early-stage construction of a bicyclic lactone skeleton in high enantiomeric excess (up to 95 %). The generated bicyclic lactone is fully primed with two desired stereocenters and enabled the synthesis of the entire family of prostaglandins according to Corey′s route. Furthermore, the reactivity and enantioselectivity of B-V oxidation of racemic bicyclic cyclobutanones were evaluated and 90–99 % ee was obtained, representing one of the most efficient routes to chiral lactones. This study further facilitates the synthesis of prostaglandins and chiral lactone-containing natural products to promote drug discovery.
