What is tricarboxylic acid?

Citric acid (CA, 2-hydroxy2, 3-propanetricarboxylic acid, tricarboxylic acid) is the largest organic acid contained in the tonnage. Generally, it is a universal plant-and animal-metabolism intermediate. CA is a commodity chemical processed and widely used around the world for plentiful pharmaceutical applications (Fig. 1) [ 1 ]. To begin with 1784, Carl Scheele (a Swedish chemist) isolated the CA (Molecular Weight: 210.14 Da) from the lemon juice. Whereas in1893, at the first time Wehmer demonstrated the culture medium includes sugars and inorganic salts, Penicillium glaucum ( Citromyces) accumulating CA. Amusingly, CA was first commercially manufactured in England from the imported Italian lemons. In 1917, Currie discovered that some of the Aspergillus niger strain generated CA into adequate nutrient mediums that contain high levels of sugar plus mineral salts and along with that preliminary medium pH (2.5–3.5). Despite these notable findings, lemon juice was still a commercial source for the manufacturing of CA until 1919. This provided the foundation for industrial CA production with Aspergillus niger [ 2 ]. As per literature, CA has been unrevealed by Krebs in the late 1930s as a key ingredient in the metabolism of all aerobe species [ 3, 4 ]. The developmental stages of the discovery and manufacture of CA from 1784 to 2020 [ 4] are represented in Fig. 2 .

What is CFTX antibiotic?

Cefotaxime sodium (CFTX) is a semi-synthetic and broad-spectrum cephalosporin antibiotic, which shows its effect against the treatment of bacterial infections. Investigators theoretically urged to create an optimal formulation, which can mitigate cytotoxicity and boost pharmacokinetic parameters through the successful focusing of bacterial cement. The CFTX pharmacokinetic parameters indicate the half-life (1 h) of the intramuscular (IM) administration of CFTX. Besides, 30% of CFTX shows protein binding and a maximal serum concentration (about 11.7 μg/mL, within 30 min). Therefore, in 2019, Valikala et al. developed pegylated CA-based CFTX-loaded dendrimers (peg-CA-CFTX) using the divergent method. The synthesis emphasizes the development of PEG diacid as the first-generation dendrimer and interacts with different active ingredients, which help generations of dimethyl form amid and thionyl chloride. Particularly, the chlorinated PEG and CA containing hydroxyl group undergoes the esterification and forms the plain form of dendrimers. The developed plan can provide adequate quantities of a product that could be used for investigating the biological activity. Additionally, it shows a better effect against bacteria (Gram-positive, and Gram-negative microorganisms). Herein, the pegylation is helped to the interaction of dendrimers with the surface of bacteria cell which resulted in the lysis if cell. In addition, the dendrimer internalization in bacterial cells has been confirmed by high fluorescence intensity (Fig. 10 ). It traced the overall hyperbranched structure that may because of the dendrimer’s immediate release after cellular component interaction. Therefore, pegylated CA-based CFTX-loaded dendrimers can be a better alternative to the conventionally engaged CFTX-loaded dosages forms [ 37 ].

What is cross linking in pharmaceuticals?

Literature reported that the straightforward process for inducing chemical or physical connections across polymer chains by supramolecular interactions or covalent bonding is called cross-linking. While many chemical cross-linking agents were used in pharmaceutical applications. But, due to large availability, lowest cost, and particularly non-toxicity, a lot of attention was paid to CA [ 4 ]. From its inceptions, assorted crosslinkers viz. epichlorohydrin, glutaraldehyde has been extensively preferred to stabilize PVA-based hydrogels. Unfortunately, such types of crosslinkers are exhibited severe toxic effects and that affects the overall applications in biomedical/pharmaceutical. In this context, the polyvinyl alcohol (PVA), CA, and silver nanoparticles (AgNPs)-based pH-sensitive drug delivery system (PVA-CA-AgNPs) has been established through green, facile, and one-step synthesis routes. In brief, Sabzi et al. developed the PVA-CA-AgNPs nanocomposites using CA as a non-toxic and green crosslinker. Fascinatingly, PVA has no required ionizable functional groups to illustrate pH-sensitive behaviors. In the main, CA is reacted with hydroxyl and amine functionalities of respective biopolymers and accordingly acts as a green crosslinker. In addition to notable properties of CA including stabilizer and crosslinker, it also provides the pH-responsive property and antibacterial activity to PVA hydrogel by the free pendant carboxylic acid of CA. Furthermore, citrate ions in PVA/CA/Ag + solution offer multiple roles such as the development of AgNPs and act as a complex-forming agent, stabilizing, and reducing agent for silver ions. The esterification reaction involving the CA containing carboxyl groups and hydroxyl groups of PVA leads to the cross-linking of PVA (Fig. 3 ). Based on that PVA/CA/AgNPs nanocomposite containing final hydrogel accomplished the desired aim through solution mixing method using water (green solvent) followed by an annealing activity. Finally, the release of ciprofloxacin (CIFLOX) from hydrogels was found to be more sustained when AgNPs assimilated in the CIFLOX-loaded hydrogel. Additionally, the combination of CA, AgNPs, and CIFLOX into the PVA matrix supplies a powerful antibacterial activity against Staphylococcus aureus ( S. aureu s). Overall, the conjugation of CIFLOX and pH-responsiveness nanocomposite hydrogels offers a green and low-cost fabrication route. Therefore, CA (green crosslinker) centered hydrogel can be a perfect promising material for colon-specific oral drug delivery and wound dressing approach [ 14 ].

What is a CA?

Citric acid (CA) is a universal plant and animal-metabolism intermediate. It is a commodity chemical processed and widely used around the world as an excellent pharmaceutical excipient. Notably, CA is offering assorted significant properties viz. biodegradability, biocompatibility, hydrophilicity, safety, etc. Therefore, CA is broadly employed in many sectors including foodstuffs, beverages, pharmaceuticals, nutraceuticals, and cosmetics as a flavoring agent, sequestering agent, buffering agent, etc. From the beginning, CA is a regular ingredient for cosmetic pH-adjustment and as a metallic ion chelator in antioxidant systems. In addition, it is used to improve the taste of pharmaceuticals such as syrups, solutions, elixirs, etc. Furthermore, free CA is also employed as an acidulant in mild astringent preparations.

What is effervescent product?

Effervescent products are variously used in pharmaceutical, nutraceutical, food, agriculture, detergent, and cleaning sectors but the major problem of the chemical and physical instability of the effervescent products during production and storage. In 2020, Paigre and co-workers reported that the co-crystallization process of CA and sodium bicarbonate (SBC) is an important component of effervescent products. CA is hygroscopic and leads in the case of a diminutive amount of moisture inducing product volatility to an uncontrollably autocatalyzed reaction in the chain. The acid amide dimer binding and co-crystal-layered structure of CA nicotinamide limits the contact between moisture and CA creates non-hygroscopic moisture and improves product stability. This study resulted in a computational investigation into moisture interactions with different crystal surfaces. In this study, nicotinamide (NIC) was preferred as a co-former molecule as widely accepted in the formulations of nutraceutical supplements. They demonstrated an application of co-crystallization to tailor the hygroscopic nature of the CA by blocks the water interaction. CA has shown its potential in the manufacturing of stabilized effervescent products, which will significantly lower acidic agents, ex. the CA, maleic acid, tartaric acid, malic acid. The sorption constant shows well the strength of the interaction of water vapor with the crystal surface and calculated with GAB and Y&N equation. They concluded that sorption CA is higher than CA-NIC co-crystal. Batch with the acidic component in the form of co-crystal, i.e., CA-NIC co-crystal, shows good stability as compared to the CA as the acidic component of the effervescent product [ 28 ]. Overall, in the future, NIC can be used as an ideal co-former for CA. There is a need to study the effect of co-crystallization on the stability of effervescent products.

What is CA in pharmaceuticals?

As per literature, CA is a multifunctional, non-toxic, ready to use, and economical monomer used for pharmaceu tical applications [ 4 ]. This is a multipurpose natural monomer and playing a crucial role in the control of metabolism, mineralization, neuronal excitations, and renal stone prevention [ 8 ]. The pharmaceutical benefits of CA may be because of the presence of three carboxy and one hydroxyl group. CA can be used to contribute prepolymer construction with diol monomers via easy, affordable, and catalyst-free thermal polycondensation that allows the formation of ester bonds and facilitates hydrolysis degradation. The pendant hydroxyl and carboxyl chemistry can be partly preserved, in order to provide inherent versatility for the majority of the substance for the conjugation of bioactive molecules during prepolymer synthesis. In this view, CA containing free pendent chemistry is essential to the production of new pharmaceutical materials with intrinsic adhesives, antioxidants, antimicrobials, fluorescent properties, etc. Due to the availed pendant carboxylate-hydroxylic chemistry, a homogenous network of hydrolyzable ester links/bonds is generated for the cross-linkage to a polymer chain in the process of an additional post-polymerization/polycondensation. Thus, CA is an attention-grabbing monomer, because of its aforesaid characteristics, which has led to the creation of a new paradigm for functional pharmaceutical materials [ 9 ]. In addition, CA is an ionic covalent interconnector of various carbohydrate polymers, which can be destroyed without the release of harmful by-products. It means an aliphatic organic acid with 3 ionizable hydrogen atoms has the additional advantage in biomedical applications [ 4, 10 ]. Another benefit of a CA containing pendant groups is that it (carboxylic groups) may be used to graft and combine other macromolecules, as necessary [ 4 ]. Notably, CA is one of the organic acids, which is approved by the Food and Drug Administration (FDA) for its pharmaceutical application and considered as generally recognized as a safe (GRAS). It may because of its biodegradability, environmentally friendly nature, ease of metabolization plus elimination, etc. [ 11, 12 ]. Therefore, its possible applications goes beyond as compared to the traditional use in food, medicines, and cosmetic products [ 4 ].

What is CA detergent?
