Drug release from porous matrixes based on natural polymers

Background: This review provides a report on recent advances in the field of drug release from matrixes made of natural polymers. Herein, the properties of natural polymers such as proteins and polysaccharides are discussed in general. Selected detailed examples of drug release profiles from biopolymer matrixes have also been collected from scientific literature and practical work, and commented on. In this review, the most common natural polymers, i.e. collagen, elastin, chitosan, hyaluronic acid and sodium alginate have been discussed as biopolymers that can be potentially applied in drug delivery systems. Methodology: The most rapidly developing field of the biomaterials science is the one dealing with their application as matrixes in drug release systems. Such systems show numerous advantages when compared to conventional ones. They improve medical treatment efficiency due to the fact that drugs are placed directly into the infected part. Moreover, the drug release systems reduce toxic reactions because the drug does not pass through the body and, as a result, does not affect the healthy tissues. Such systems also improve the patient?s comfort during the treatment. Result: Biocompatibility, bioresorbability and non-toxicity are the significant properties characteristic for natural polymers. Natural polymers can be used to obtain biomaterials which can further find their applications in the production of bones or soft tissues implants as well as dressing materials placed on damaged skin. Nevertheless, the disadvantages of biomaterials made of natural polymers, e.g., high solubility and low thermal stability, limit the range of their potential applications. Therefore, it is necessary to modify material properties by carrying out the cross-linking process. Conclusion: Recently, a rapidly growing interest in the use of porous materials as controlled drug delivery matrixes has been observed since they present several positive features. The drug release from polymeric matrixes is based on the carrier degradation process which depends on dissolving and diffusion processes. The selection of a polymeric matrix depends on its compatibility with the drug as well as the manufacturing process which needs to be considered. The proper adjustment of the drug release rate is necessary to obtain the best results during medical treatment. Numerous classes of hydrophilic as well as hydrophobic drugs can be released from polymeric matrixes which is beneficial to medical treatment. The research of different drug release systems has already been carried out, and the results can be found in scientific literature.

This invention is to provide quinazolinone derivatives, and their acid salts and quaternary ammonium salts, having an effect of preventing or treating diseases caused by calcium ion overload in cells, such as ischemic heart disease, ischemic cerebral disease and ischemic renal disease, and their usage. The quinazolinone derivatives are represented by the formula: STR1 typically, T represents an oxygen atom; Y represents a phenyl or cyclohexyl group; R1 represents a hydrogen or chlorine atom; R2 represents a hydrogen atom; ring W represents a benzene or pyridine ring; Z represents a group of the formula: STR2

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Synthetic Route of 67496-78-0, you can also check out more blogs aboutSynthetic Route of 67496-78-0

Aceclidine and pilocarpine interact differently with muscarinic receptor in isolated rabbit iris muscle

The relationship between muscarinic receptor affinity states and the contractile response to the muscarinic agonists carbachol, aceclidine, and pilocarpine, has been examined in the isolated rabbit iris muscle. Contraction of the iris muscle by carbachol and aceclidine was more potent and/or more efficacious than the response to pilocarpine. Analysis of [3H]- Quinuclidinyl benzilate (QNB) binding showed that while both carbachol and aceclidine bound to high- and low-affinity forms of the muscarinic receptor, pilocarpine bound to one affinity state. The efficacy of carbachol and aceclidine to stimulate contraction of the iris muscle was consistent with receptor occupancy theory only when considering the low-affinity state of the muscarinic receptor, and activation of the low-affinity rather than high-affinity binding state of the receptor is likely to mediate the contraction of iris muscle. Therefore, the typical anti-glaucoma muscarinic agonists aceclidine and pilocarpine may interact differently with their target receptors in isolated rabbit iris muscle.

Directed synthesis of noncentrosymmetric molybdates using composition space analysis

A systematic investigation of the factors governing the reaction product composition, hydrogen bonding, and symmetry was conducted in the MoO 3/3-aminoquinuclidine/H2O system. Composition space analysis was performed through 36 individual reactions under mild hydrothermal conditions using racemic 3-aminoquinuclidine. Single crystals of three new compounds, [C7H16N2][Mo 3O10]¡¤H2O, [C7H 16N2]2[Mo8O26] ¡¤H2O, and [C7H16N2] 2[Mo8O26]¡¤4H2O, were grown. The relative phase stabilities for these products are dependent upon the reactant mole fractions in the initial reaction gel. This phase stability information was used to direct the synthesis of two new noncentrosymmetric compounds, using either (S)-(-)-3-aminoquinuclidine dihydrochloride or (R)-(+)-3-aminoquinuclidine dihydrochloride. [(R)-C7H 16N2]2-[Mo8O26] and [(S)-C7H16N2]2[Mo8O 26] both crystallize in the noncentrosymmetric space group P2 1 (No. 4), which has the polar crystal class 2 (C2). The second-harmonic generation activities were measured on sieved powders. The structure-directing properties of the molybdate components in each compound were determined using bond valence sums. The structures of all five compounds were determined using single-crystal X-ray diffraction.

A practical chemoenzymatic process to access (R)-quinuclidin-3-ol on scale

(¡À)-3-Butyryloxyquinuclidinium butyrate 6 (2 M, 571 g/L), prepared from (¡À)-quinuclidin-3-ol 1 and butyric anhydride, undergoes enantioselective hydrolysis by an Aspergillus melleus protease {1.0% (w/v)} in water in the presence of Ca(OH)2 to keep the reaction at pH 7 and trap butyric acid that is introduced as part of (¡À)-6 and generated by the enzymatic hydrolysis. After a 24 h period, extraction with n-heptane provides (R)-quinuclidin-3-yl butyrate 5a, which, on methanolysis with Na2CO3, is converted into (R)-1, a common pharmacophore of neuromodulators acting on muscarinic receptors, in 96% ee and 42% overall yield from (¡À)-1. The unwanted antipode (S)-1, which is extracted into n-butanol and purified via its hydrochloride salt in 89% ee and 40% overall yield from (¡À)-1, can be racemized by the catalysis of Raney Co at 140C under an atmosphere of H2 (5 kg/cm2) to regenerate (¡À)-1 in 97% yield.
