Abstract
Leukemia is an incurable disease; it exhibits strong resistance to chemotherapy and other therapies, and it represents the most common childhood cancer and mortality. The cytotoxic of amygdalin (AMG) against the cell line of human monocytic leukemia (THP-1) was recorded, before determining other pharmacological effects. The cells were exposed to AMG for 24 hr at 37°C at different concentrations, the cytotoxic effect was determined via the MTT assay. The cells and the supernatant were collected for analyzing the oxidant/antioxidant status, apoptotic markers, and anti-microbial activity. Results showed a marked anti-proliferative cytotoxic effect of AMG which is concentration and time-dependent, the lipid peroxidation content was significantly decreased while the total thiol was increased in the treated cell line, significant up-regulation of Caspase-3 (Cas-3) and Bcl-2-associated X protein (BAX) and down-regulation of B-cell lymphoma 2 (Bcl-2). Furthermore, The bacterial activity was detected via Minimum Inhibitory Concentration (MIC), Minimum Bactericidal Concentration (MBC), and Disc Diffusion assays, while the antifungal evaluation was done by the Minimum Fungicidal Concentration (MFC). Antimicrobial experiments revealed that AMG exerted potent, broad-spectrum antimicrobial effects toward a diversity of dangerously infecting pathogens. In conclusion; the prevailing research suggests that AMG is an effective anticarcinogenic and antimicrobial substance. The utilization of AMG subsequently in masks or wound dressings to prevent bacterial & fungal infections, including mucormycosis following COVID-19, as well as infections caused by penicillium and aspergillus, is a highly effective strategy in combating resistant microorganisms.

Jumaa AH, Abdulkareem AH, Yasin YS. The Cytotoxic Effect of Ciprofloxacin Laetrile Combination on Esophageal Cancer Cell Line. Asian Pac J Cancer Prev 2024; 25:1433-1440. [PMID: 38680005 PMCID: PMC11162738 DOI: 10.31557/apjcp.2024.25.4.1433] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2024] [Accepted: 04/07/2024] [Indexed: 05/01/2024] Open
Abstract
OBJECTIVE aim of this study was to examine the synergistic effect between the antibacterial drug ciprofloxacin and the natural compound laetrile on esophageal cancer cells, specifically focusing on their combined cytotoxic effect. METHODS The combined cytotoxic effects of two alternative incubation durations (24 and 72 hours) were studied using an esophageal cancer cell line. Ciprofloxacin, laetrile, and their combinations were tested at concentrations ranging from 1 to 1000 micrograms/milliliter, to enhance the safety of the combination, the concentrations of the combination constituents were reduced by half compared to when they are used individually, the combination index was then calculated to estimate the components' possible synergistic effects. RESULT The results indicate that the combined cytotoxicity of ciprofloxacin and laetrile was greater than the cytotoxicity of either ciprofloxacin or laetrile alone, the combination cytotoxicity increased with higher concentrations and longer incubation periods, in other words, the cytotoxicity pattern of the combination was time-dependent (cell-cycle specific), and concentration dependent, (cell-cycle non-specific). CONCLUSION The study found that the combination of ciprofloxacin and laetrile had a greater inhibitory effect on the growth of esophageal cancer cells compared to ciprofloxacin or laetrile alone. This suggests a synergistic effect between the components of the mixture, which can be attributed to a complementary mechanism between the ingredients in the combination.

Hwang JH. Single-Dose Toxicity Study of Intramuscular Neuralgia-Pharmacopuncture Injection in Rats. J Pharmacopuncture 2023; 26:348-356. [PMID: 38162467 PMCID: PMC10739476 DOI: 10.3831/kpi.2023.26.4.348] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2023] [Revised: 10/16/2023] [Accepted: 10/31/2023] [Indexed: 01/03/2024] Open
Abstract
Objectives Neuralgia-pharmacopuncture (NP) was recently developed as a water-soluble type of pharmacopuncture inspired by CS (care special pain)-pharmacopuncture. I aimed to evaluate the toxic response and approximate lethal dose of when NP when administered intramuscularly to Sprague Dawley rats. Methods The experimental group was divided into the NP test substance group and the saline control group and administered at a dose of 1.0 mL/animal to the posterior thigh muscles on both sides using a 1 mL syringe; each group consisted of five males and five females. Each rat was monitored for clinical signs and changes in body weight for 14 days after a single intramuscular injection. After completing observation, necropsy findings and localized tolerance at the injection site were assessed via gross necropsy and histopathological examination. Results No deaths occurred in the NP or control group, regardless of sex. During the observation period, no changes (such as general symptoms, weight change, or visual observation results at the time of autopsy) were judged to be due to the test substance. Histopathological examination showed no changes at the administration site judged to be caused by the test substance in either the male or female test substance administration groups. In addition, mononuclear cell infiltration of the outer membrane of the femoris muscle at the administration site was observed at the same frequency and extent in the control and NP groups, and was judged to be caused by physical stimulation by the injection needle; therefore, it had no toxicological significance. Conclusion Based on the above results, the approximate lethal dose for a single intramuscular administration of the test substance NP in Sprague-Dawley rats was judged to be > 1.0 mL/animal, and there were no findings that were judged to be due to the test substance at the administration site.

Amygdalin as a Promising Anticancer Agent: Molecular Mechanisms and Future Perspectives for the Development of New Nanoformulations for Its Delivery. Int J Mol Sci 2023; 24:14270. [PMID: 37762572 PMCID: PMC10531689 DOI: 10.3390/ijms241814270] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2023] [Revised: 09/14/2023] [Accepted: 09/15/2023] [Indexed: 09/29/2023] Open
Abstract
Cancer rates are increasing, and cancer is one of the main causes of death worldwide. Amygdalin, also known as vitamin B17 (and laetrile, a synthetic compound), is a cyanogenic glycoside compound that is mainly found in the kernels and pulps of fruits. This compound has been proposed for decades as a promising naturally occurring substance which may provide anticancer effects. This is a comprehensive review which critically summarizes and scrutinizes the available studies exploring the anticancer effect of amygdalin, highlighting its potential anticancer molecular mechanisms as well as the need for a nontoxic formulation of this substance. In-depth research was performed using the most accurate scientific databases, e.g., PubMed, Cochrane, Embase, Medline, Scopus, and Web of Science, applying effective, characteristic, and relevant keywords. There are several pieces of evidence to support the idea that amygdalin can exert anticancer effects against lung, breast, prostate, colorectal, cervical, and gastrointestinal cancers. Amygdalin has been reported to induce apoptosis of cancer cells, inhibiting cancer cells' proliferation and slowing down tumor metastatic spread. However, only a few studies have been performed in in vivo animal models, while clinical studies remain even more scarce. The current evidence cannot support a recommendation of the use of nutritional supplements with amygdalin due to its cyano-moiety which exerts adverse side effects. Preliminary data have shown that the use of nanoparticles may be a promising alternative to enhance the anticancer effects of amygdalin while simultaneously reducing its adverse side effects. Amygdalin seems to be a promising naturally occurring agent against cancer disease development and progression. However, there is a strong demand for in vivo animal studies as well as human clinical studies to explore the potential prevention and/or treatment efficiency of amygdalin against cancer. Moreover, amygdalin could be used as a lead compound by effectively applying recent developments in drug discovery processes.

Abstract
The important periodontal disease pathogen Porphyromonas gingivalis produces thick biofilms that increase its pathogenicity. Finding natural antimicrobial agents is crucial because of the rise in antibiotic resistance. The purpose of this study was to determine if plant extracts such as Symphytum officinale (S) and Panax Ginseng (G) were effective against P. gingivalis separately and in combination with a common antibiotic, metronidazole (F). Six different dilutions were produced using the plant extracts in different concentrations and antibiotics separately and in combination with F, G, and S using the two-fold serial dilution technique. To evaluate the effects of these substances, biofilm inhibition experiments were conducted. Plaque samples were collected from periodontitis patients to isolate P. gingivalis, and a standard strain of P. gingivalis (ATCC 33277) was purchased. Additionally, Acylated Homoserine Lactones (AHLs) detection was carried out to look for any activity that would interfere with quorum sensing. GraphPad Prism was used for statistical analysis with a p-value < 0.05. The combinations of Symphytum officinale and metronidazole (S+F) showed the maximum effectiveness in biofilm inhibition (98.7%), which was slightly better than G+F (98.2%), with substantial variations in biofilm inhibition levels in different treatment regimes. Notably, the patient isolate was more active than the standard strain. Additionally, the plant extracts and their combinations at particular dilutions had notable inhibitory effects on the generation of AHL (p < 0.05). The study highlights the possibility of Symphytum officinale and Panax Ginseng as effective treatments for P. gingivalis biofilm and AHLs, both on their own and in combination with metronidazole. These organic substances may open the door to cutting-edge methods of treating periodontal disorders.
