This paper reports the development of a successful anti-solvent method that incorporates colloidal nano scale graphene oxide (nGO) directly into hydrophobic drug crystals. The nGO dispersed in solution acted as nucleating sites for crystallization and were embedded into the drug crystals without altering its structure or physical properties such as melting point. Several composites of drugs Sulfamethoxazole and Griseofulvin were synthesized with nGO concentration ranging between 0.2 and 1.0 %. The presence of nGO dramatically enhanced the dissolution rate. The time needed to reach a 50 % release (T50) reduced from 42?14 min with the integration of 0.8 % nGO in SMZ, while in GF the reduction was from 44?27 min with 0.5 % nGO. Increased release rates are attributed to the presence of the hydrophilic nGO which hydrogen bond more so with the aqueous mediums. Therefore, the incorporation of nGO into poorly soluble drugs is an effective approach towards drug delivery and bioavailability improvement and opens a new approach to high performance drug delivery.

Lamellarins are marine alkaloids containing fused 14-phenyl-6H-[1]benzopyrano[4?,3?:4,5]pyrrolo[2,1-a]isoquinoline or non-fused 3,4-diarylpyrrole-2-carboxylate ring systems. To date, more than 50 lamellarins have been isolated from a variety of marine organisms, such as mollusks, tunicates, and sponges. Many of them, especially fused type I lamellarins, exhibit impressive biological activity, such as potent cytotoxicity, topoisomerase I inhibition, protein kinases inhibition, and anti-HIV-1 activity. Due to their useful biological activity and limited availability from natural sources, a number of synthetic methods have been developed. In this chapter, we present an updated and comprehensive review on lamellarin alkaloids summarizing their isolation, synthesis, and biological activity.

alpha-Damascone is widely used in perfumes. However, the manufacture of alpha-damascone remains challenging owing to the limitations of current production processes. Herein, alpha-damascone was successfully synthesized from alpha-ionone using a new route involving only four steps, namely oximization, epoxidation, dehydration, and reduction. The total yield was 54.9% with a final chemical purity of 97% (by GC). Only water, cyclohexane, and ethanol were used in the reactions except in the purification step, and all solvents could be recycled. The structures of the intermediates and target compound were identified by 1H NMR and 13C NMR analyses and MS experiments. This route is a simple and successful method for the industrial preparation of alpha-damascone.

Background: Chalcones holding arylic substitutions and pyrazolic chalcones were reported as potent antimicrobial and antioxidant agents. Prompted by the literature, it was considered of interest in the present work to develop the bioactive materials incorporating five, and six-membered ring heterocycles in a single molecular framework with above molecules. Methods: Synthesis of chalcone derivatives derived from condensation of 2-(3,5-dimethyl-pyrazol-1- yl)-1-phenyl-ethanone and aldehydes has been discussed. Sodium hydride was employed as catalyst to facilitate the reaction which proved to be a worthy catalyst over NaOH and KOH. This protocol offers advantages such as easy workup, shorter reaction time and promising yield for the synthesis of chalcones. Further, another aromatic ring was installed to the chalcones to obtain pyrimidine, isoxazole, and pyrazole derivatives. The structures of the prepared compounds were confirmed by FT-IR, 1H NMR, 13CNMR spectroscopy, Mass spectrometry and elemental analysis. The biological activity of the compounds against four bacterial strains namely Bacillus subtilis, Pseudomonas aeruginosa, Staphylococcus aureus, Escherichia coli and three fungal strains have been evaluated. Results: An improved process for biologically useful chalcone derivatives has been discussed providing overall good yield. The newly synthesized compounds were screened for in vitro antioxidant and antimicrobial activity. Based on the preliminary results, compounds 5c, 6c, 6d in this series showed significant activity against tested bacterial strains. Compounds 6b, 6c, 6d and 7b showed potent inhibitory activity against fungal growth. Among them, compound 6c displayed the most potent activity against Candida parapsilosis, Candida tropicalis, Candida albicans, which was comparable with standard drug fluconazole. Conclusion: Synthesis, characterization and biological evaluation of new heterocyclic pyrazole chalcones has been described. The method of preparation of these compounds is very straightforward and free of tedious work up as well quite time saving. All the compounds have shown moderate to good inhibitory activity against B. subtilis and exhibited mild to moderate antibacterial activities against the other tested organisms.

The attractive biological activity profiles of many heterocyclic moieties put them in the category of compounds having a variety of pharmacological therapeutic activities. Although lots of heterocyclic moieties have been studied for their anti-cancer activity, the present review emphasizes on heterocyclic compounds having moieties like oxadiazole, quinoline, isoxazoles and nicotinonitrile containing Nitrogen, Oxygen, and Sulphur in the heterocyclic ring structures, together with the substituent groups of the core scaffold. Their practical application ranging from extensive clinical use to fields as diverse as medicine has perched them as the true cornerstone of medicinal chemistry and their prominence lies in their study about their strong impact on the physicochemical properties. But their most important role in cell physiology and as probable intermediates for numerous biological reactions leading to anticancer research and thus capitalizing on the intrinsic versatility and dynamic core scaffold of these compounds has put them in the most significant category. In this current review, the recent advances made on the anticancer therapeutic potential of the above mentioned aromatic heterocyclic compounds effective against human tumor/ cancer cell lines has been discussed. Their structure-activity relationships, mechanism of action and suppression activity along with the importance of the substitution pattern has also been dealt with.

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.Recommanded Product: Isoxazole, you can also check out more blogs about288-14-2

87988-94-1, Name is 5-Methylisoxazol-4-amine, belongs to isoxazole compound, is a common compound. COA of Formula: C4H6N2OIn an article, once mentioned the new application about 87988-94-1.

4-Aminoisoxazoles can be acylated with a wide variety of activated carboxylic acids.Hydrogenation of the resulting amides gives alpha-(acylamino)enaminones, which cyclize to 4(5)-acylimidazoles upon treatment with base.This method allows for the synthesis of acylimidazoles with a wide range of substituents at C-2.Utilization of N-substituted 4-aminoisoxazoles in the same sequence of reactions yields 1-substituted 5-acylimidazoles, a substitution pattern not otherwise easily prepared.Treatment of alpha-(acylamino)enaminones, derived from N-unsubstituted isoxazoles, with primary amines leads to incorporation of the amine at the beta-position with concomitant expulsion of ammonia.This sequence efficiently yields 1-substituted and 1,2-disubstituted 4-acylimidazoles but does not give satisfactory yields of 5-substituted 4-acylimidazoles due to steric inhibition of the amine exchange.

Carbon monoxide represents the most important C1-building block for the chemical industry, both for the production of bulk and fine chemicals, but also for synthetic fuels. Yet its toxicity and subsequently its cautious handling have limited its applications in medicinal chemistry research and in particular for the synthesis of pharmaceutically relevant molecules. Recent years have nevertheless witnessed a considerable headway on the development of carbon monoxide surrogates and reactor systems, which provide an ideal setting for performing carbonylation chemistry with stoichiometric and substoichiometric carbon monoxide. Such setups are particularly ideal for the introduction of isotope labels such as carbon-11, carbon-13, and carbon-14 into bioactive compounds. This review summarizes this growing field and examines the large number of carbonylation reactions that can be exploited for the introduction of a carbon isotope.
