It is still difficult to use tissue engineering to return damaged bones back to how they were originally intended. Due to recent advances in 3D printing, together with the introduction of new materials and technological assistance, the basis for BTE has been established. Biological 3D biomaterials have cells inside them, which allows for the creation of structures that mimic real tissues. Microextrusion, inkjet, and laser-assisted bioprinting are the three primary methods used in 3D bioprinting manufacturing. Hydrogels packed with cells, growth hormones, and bioactive ceramics are among the bioinks utilized in bone bioprinting. With the use of magnetic resonance imaging or computed tomography scanning, 3D printing offers substantial benefits for tailored treatment by enabling the creation of scaffolds with the right structural qualities, form, and dimensions. Three-dimensional (3D) bioprinting is a cutting-edge technique that has been utilized recently to create multicellular, biomimetic tissues with layers upon layers of intricate tissue microenvironment printing. We approached the use of hydrogels with great strength in 3D printing for BTE with an emphasis on first providing a thorough study about the development of 3D printing, printing techniques, and ink selection in this review. A brief prediction on how 3D printing would advance in the future was made.","PeriodicalId":10926,"journal":{"name":"Current Organic Chemistry","volume":"24 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141512792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Staphylococcus aureus is the most dangerous Grampositive bacterium among staphylococcal bacteria. Moreover, resistance to Mycobacterium tuberculosis is an urgent public health issue. In this sense, cinnamic acid and acetamide derivatives have been used as strategic nuclei in the design of antimicrobial agents. With the aim of investigating whether antibacterial activity is improved with the junction of cinnamic and acetamide nuclei, cinnamic amidoesters were planned and evaluated as potential antibacterial agents. In silico (ADMET test and molecular docking) and in vitro (antibacterial and antituberculosis evaluation, and toxicity on Artemia salina larvae) studies were performed. Twelve cinnamic amidoesters were synthesized, which present positive characteristics for possible drug candidates, and showed subtle activity against E. coli, however, against S. aureus, unsubstituted and para-substituted compounds (R3 = H, Me, Cl, Br) showed significant activity, with MIC = 156.25-625 μg.mL-1. Only one para-substituted compound (R3 = Bu) showed discrete activity against M. tuberculosis, with MIC = 200 μM. For the most active compounds against S. aureus, the molecular docking study demonstrated affinity with the TtRNA enzyme, which plays a central role in the assembly of amino acids into polypeptide chains. The most active compounds against S. aureus and M. tuberculosis were non-toxic on A. salina, with LC50 > 1000 μg.mL-1. According to in silico/vitro studies, the non-toxic compound 5h (R3 = Cl) stands out as a potential antibacterial agent for further studies.","PeriodicalId":10926,"journal":{"name":"Current Organic Chemistry","volume":"1 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141512791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Macromolecular drug conjugates of aceclofenac were prepared by employing pectin, β cyclodextrin, deacetylated chitin (chitosan) and albumin (egg and bovine serum). The prepared conjugates were characterized and tested for their antiinflammatory, antinociceptive and antiulcerogenic activity. Further experimentation was undertaken to analyze the behavior of compounds and their stability in hydrolytic conditions. Test compound A1, a pectin conjugate of aceclofenac, exhibited significant antinociceptive and anti-inflammatory activity with a significant decrease in ulcer index (4.45±0.24) as against aceclofenac (8.61±0.40) or vehicle (12.39±0.44) treated group.

Numerous patents have been filed for the synthesis of quinoline-based compounds, discussing about their derivatives and uses. Here, we have discussed the methods of quinoline synthesis, structural alterations, and patents showing its importance in various industries. Quinolines have been investigated as antimalarial substances, with substances, like quinine and chloroquine, serving as notable examples, and they have also been investigated to possess anti-inflammatory, anti-tumor, and CNS activity. The synthesis of quinoline is also subjected to several recognized procedures. The variations in the ring system and various synthetic approaches are the key highlights of the article, and it includes the various catalysts that could be recycled and reused by the assisted technique, which increases the yield and requires less time for the synthesis (ultrasound-promoted synthesis, one-pot reaction, and microwave and photocatalytic reactions).

Compound 3,19-Di-Oacetylandrographolide (3,19-DAA) or (4) is produced by acetylating compound (2). Compounds (2) and (4) have been investigated for their cytotoxic effects on three human cancer cell lines (SK-LU-1, Hela, and HepG2) using the MTT method. Compound (4) demonstrated significant cytotoxicity against all three cancer cell lines, with IC50 values ranging from 8.38 to 10.15 μM. This represents an increase in cytotoxicity of 2.67 to 3.12-fold compared to compound (2). One way to deal with the problem of low water solubility is by encapsulating (4) into liposomes using a thin-film hydration technique. The optimal conditions for maximizing encapsulation efficiency involve molar ratios of phosphatidylcholine, 3,19-DAA, and cholesterol at 4:1:1. Encapsulating compound (4) within nanoscale liposomes increases its water solubility compared to the free form of compound (4). Pose 324 of compound (4) demonstrated the best conformation among 500 docking conformations when docked to enzyme 1T8I in a silico docking study. The free Gibbs energy and inhibition constant were determined to be -7.09 Kcal/mol and 6.32 μM, respectively. These values help elucidate the strong interaction between compound (4) and the enzyme in the ligand interaction model. The molecular dynamics simulation using Desmond software in the Linux environment was conducted for a duration of 0 to 100 nanoseconds on the complex formed by pose 324 and 1T8I. The results showed effective interactions within the complex, with stability observed from 0 to 60 nanoseconds. Throughout the simulation, specific amino acids such as Ala 499 (involved in 90% of the simulation time with hydrogen bonding via a water bridge) and Thr 501 (involved in 50% of the simulation time with one hydrogen bond via a water bridge) were found to play significant roles. The majority of torsion bondings are C-O bondings in the acetyl group of compound (4), with torsion energy values of 13.47 Kcal/mol. Carbon atom C-29 at position 324 exhibits the highest fluctuation.","PeriodicalId":10926,"journal":{"name":"Current Organic Chemistry","volume":"98 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141172223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under the same optimized reaction conditions, along with aryl or heteroaryl aldehydes, aliphatic aldehydes also underwent a smooth reaction and afforded the desired products in excellent yields. All the synthesized compounds were obtained pure in excellent yields by simple filtration and washing subsequently with ethanol. The use of less toxic solvent, low-cost, commercially available metal-free organocatalyst, no column chromatographic separation, good yields, and easy isolation procedure are some of the major advantages of this newly developed protocol.","PeriodicalId":10926,"journal":{"name":"Current Organic Chemistry","volume":"45 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140937487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
