Discover of No-Side Effect Phenytoin Drug from Catharanthus Roseus Plant


 Phenytoin drug is commonly used for seizures and breast cancer, but chemically prepared phenytoin drug has more side effect. Herein, we have discovered phenytoin drug (100%) without side effect from Catharanthus Roseus (CR) plant using a photon-induced method (PIM). The pure plant (absence of metal nanoparticles) synthesized by green chemistry offers a novel and potential alternative to non-chemically synthesized Catharanthus Roseus nano-sized particles (CR-NPs,) studied for the first time. The GC-MS analysis of CR-NPs provides all peaks determining the presence of phenytoin compound and 1H NMR analysis of chemical shift conformed phenytoin structure. The XRD analysis results in highly crystalline material and crystallite size is 25 nm. The CR NPs highly killed breast cancer cells (MCF-7 cell-lines), while without killed the normal cells (VERO cell-lines). Our findings brought new insights into the development of nano-sized plant exerting strong next generation of no-side effect nature drug.


Background
Nano-scale research, the use of innovative medicinal prepared at nano-scale levels is widespread worldwide. The researchers make an effort to discover an eco-friendly process for the fabrication of green nanoparticles (NPs). 1 The green synthesis has great attention to synthesizing metal NPs from medicinal plants and these NPs has been multifunctional and has an interesting application in agricultural, medical, and physical elds [2]. Currently, NPs are crucial in producing sustainable technologies for modern society. Nanotechnology has several drawbacks such as high-cost processing, di cult to manufacture and incorporates nano-pollution, which is extremely dangerous for living organisms. 3,4 Developing NPs for drug delivering system is extensive due to the use of chemicals as a detergent that impacts on climate. In addition, drug delivery with NPs demonstrates toxicity, predictable gelation tendency, alveolar in ammation, and burst release. 5,6 The literature studies on the biosynthesized of metal NPs from an extract of the plant are common. But, the current work reports on employing a novel PIM technique for tapping the rich reservoirs of bioactive materials as CR NPs from CR plants. PIM created the nanopackets of active metabolites that revealed improved solubility in solvents and enhanced biologically active pharmaceutical properties. Nowadays, NPs synthesized from medical plants, as therapeutic agents gain much more attention compared to conventional therapy nano-medicine, have side effects on human healthcare. Moreover, eco-friendly biosynthesized of plant NPs is may have a huge impact on the control of various chronic diseases. 7,8 GC-MS technique can be employed for the study the bio-synthesized NPs and measuring the amount of some active principles in plants utilized in drugs, pharmaceutical, food or cosmetic industry. [9][10][11][12] The reported literatures on the extract materials in the investigation has demonstrated that so far there are no published papers worldwide, related to the possible nature components of biosynthesized plant NPs.
Herein, we report the discovery of Phenytoin component that directly sense CR plant. In this study, attempted to synthesize green NPs (without metal trapping) evaluate as a potential breast cancer cell lines. The pure biological synthesis of plant NPs may be most effective and provide an option to decrease the cytotoxicity, price and side effects. The production of Phenytoin from CR plants could be considered infers to the fabrication of new life-saving drugs and may have elucidated as a better alternative relative to the plant-mediated metal NPs and allopathic medicine.

Results And Discussion
To explore the crystallinity of the synthesized CR-NPs, XRD technique was conducted in the range of 05-80°. Figure 1  (104), respectively. The above lattice plane value con rmed highly crystallite to smaller nanoparticles are formed in the case of CR-NPs are correlated to DLS and TEM measurements. The unassigned peaks, which may have occurred may be attributed to the crystalline and amorphous organic agents. The average crystalline size was evaluated from the XRD data employing the Debye-Scherrer formula. The size was found to be 25 nm in the case of CR-NPs. 13 The novel fabrication of CR-NPs compared with standard JCPDS le is not available before. The FTIR pattern of the leaf plant of CR-NPs is revealed in Figure 1b. The absorption bands at 3420 cm -1 correspond to the O-H stretching vibration. The peaks at 2922 and 2842 cm -1 are related with symmetric stretching and anti-symmetric of CH 2 , respectively. The peak for the carbonyl groups was located at 1630 cm -1 due to asymmetrical COO− stretch. 14 The carbonyl group from the amino acid and protein had a stronger capability to bind in nano-size plant particles. The low absorption peak at 1058 cm -1 is associated to C-O aromatic and aliphatic amines. 15 The intensive absorption peaks at 606 cm −1 correspond to the CR-NPs. 16 Figure 1c and d show the UV-visible diffusion re ectance data modi ed Tauc plot. The optical direct and indirect bandgap energy (Eg) estimated from Tauc's plot was found to be 3.5 eV (Figure1c) and 3.09 eV (Figure1d). 17 These remarkably good performances can be attributed to the indirect bandgap pure plant for visible-light absorption e ciency. These data reveal that the CR-NPs can be explained by the reduced crystallinity, as shown in XRD analysis. The grain size and zeta potential was analysed by dynamic light scattering (DLS). The grain size of the green prepared CR was 19 nm with a 0.209 of PDI value. The single peak implied that the high-quality of the prepared CR plant for nano-sized particles, as shown in Figure 2(a). The peak was obtained with a wide base of CR-NPs were found in the solution. The zeta potential of the CR-NPs was −0.3 mV as shown in Figure 2(b), this results signifying the presence of repulsion among the synthesized nano-sized plant particles. 18 It is obvious that the CR-NPs are polydispersed in nature owing to its negative zeta potential and is also has long-term stability in the solution. 19 The results of FTIR was indorse the stability of CR-NPs, where it exposed two distinct peaks at 3420 and 1630 cm −1 .
TEM images of lower and higher magni cation showed spherical shapes. The CR-NPs (Figure 3a, b, c) showed an average particle size varying from 10 nm to 20 nm. The nano-size particles strength avoids the passing of dissimilar molecules of protein created during the method of biosynthesis. The nano-size particles having variable sizes and shapes was observed in common the biological organizations. 20 The TEM morphology showed in clear lattice fringes can be labelled for nanoparticles and attributed to the presence of well-crystalline NPs, as shown in Figure 3(d). EDS measurements were performed, as shown in Figure 4. The weight percent of C (53%), O (37%) and K (10%) were obtained for CR-NPs. These results indicate that CR-NPs have more % of carbon and oxide elementals presented. 1 HNMR analysis reveals a chemical shift of CR-NPs, as shown in Figure 5(a). The exhibiting different peaks, two of which assigned to the CDCL 3 utilized as a solvent. The main peak at 7.19 ppm corresponds to the protons of the aromatic rings. In the meantime, all the 10 protons in the structure are magnetically equivalent due to molecular equilibrium, only a single integrated signal is detected. Also, the existence of the signals only of the aromatic protons implies that phenytoin is the only compound. 21 GC-MS analysis was used to study the chemical constituents of the CR-NPs. The test revealed that the presence of 100% phenytoin compound, as shown in Figure 5 Table 1. The compounds are identi ed by the mass spectroscopy were presented. The total numbers of compounds identi ed in the nano-sized CR plant was found as the both major and minor peak such as phenytoin compound. While micro-size particles of CR plant above 40 compounds presented was reported earlier. 22,23 The nano-size plant of CR leaves, GC-MS results to conformed Phenytoin compound well match with CAS-57-41-0. The phenytoin compound highly bioactive of seizures, breast cancer, and diabetes.

In-Vitro Cell Lines with No-side effect of CR-NPs
The in vitro cytotoxicity assay was conducted on normal cell lines (VERO), as shown in Figure 6. The control sample shown in Figure 6(a) and CR-NPs are non-toxic and reverts the non-toxic effect in normal cell lines as, shown in Figure 6(b). The viability (%) of the NPs was illustrated through MTT assay within the VERO cell line, which showed that the CR-NPs understudy has good cell viability at all the tested concentrations ( Table 2). The biological role of metal nanoparticles in identi cation and bioremediation of human cancers gained a good interest today, but all methods were both cancer and normal cells were killed. However, the pure plant of Catharanthus Roseus has attained a good name within the eld of medication because of their distinctive properties that obvious therapeutic potential within the identi cation and treatment potential within some human cancer sorts. But, CR plant for micro-sized particles takes treatment was a protracted time and toxic. Herein, CR micro-size converted into nano-sized CR plant for no-side effect, which con rmed in above results for the rst time.

The control sample (MCF-7) is shown in Figure 7(a). Toxicity rate against MCF-7 cell lines will increase with the increase within the concentration of CR-NPs, as shown in Figure 7

Conclusion
In summary, we discovered plant nano-sized particles via facile synthesis method (PIM) for highly effective no-side effect bioactive application. A novel technological achievement for the preparation of nano-sized plant powder was described and reported for the rst time. The XRD, DLS and TEM results con rmed nano-size particles and highly crystalline particles. 1  In vitro cytotoxicity of the CR-NPs Procedure. The MCF 7 cancerous and VERO normal cells were provided from National Centre for Cells Sciences. The cells were supplemented 10% fetal bovine serum (FBS) in Eagle's MEM. The samples were attained at 37ºC with 5% carbon dioxide and 95% air conditions. The culture medium was checked and maintained frequently as well as replaced twice a week.
Cells treatment protocol. The cultured cells were separated with trypsin ethylene diamine tetra acetic-acid, then viable cells were measured employing a diluted hemo-cytometer possess 5% FBS (1x10 5 cells/ml). Afterward, a 0.1 ml of cells solutions were added into 96-well plate at a density of 10,000 cells/well. The cells were incubated at 37 ºC with 5% carbon dioxide and 95% air. After one day of incubation, the suspensions were modi ed with serial contents of the prepared NPs. The samples were dispersed in dimethylsulfoxide and sample dispersion was diluted twice and the required nal test amount with serum free medium. Another four serial dilutions were performed to provide a total of ve sample concentrations. A solutions of 0.1 ml of the diluted samples were inserted to the suitable wells, which having 0.1 ml of cultured media. The plates were maintained for two days at 37 ºC with similar conditions. The medium-only sample was acted as reference and triplicate was attained for all contents.
MTT assay. The mitochondrial enzymes in organ cell called succinatedehydrogenase cleave the tetrazolium and dissolving the MTT to an insoluble purple formazan. Thus, the produced formazan is precisely proportional to the viable cells number. After 2 days, 15 µl of MTT (5 mg/ml) in phosphate buffered saline was seeded to each well and kept at 37 ºC for 4 h. Then, the media with MTT were icked off and the developed formazans were added in 100 µl of DMSO. Finally, the absorbance was recorded at 570 nm utilizing micro-plate reader. 28,29 Declarations NOTES The authors declare no competing nancial interest.
