Enhancement of Antibacterial Activity of Paludifilum halophilum and Identification of N-(1-Carboxy-ethyl)-phthalamic Acid as the Main Bioactive Compound. BIOMED RESEARCH INTERNATIONAL 2020; 2020:4805706. [PMID: 32104693 PMCID: PMC7038168 DOI: 10.1155/2020/4805706] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/31/2019] [Revised: 11/03/2019] [Accepted: 12/12/2019] [Indexed: 11/17/2022]
Abstract
The aim of this study was to determine the combined effect of fermentation parameters and enhance the production of cellular biomass and antibacterial compounds from Paludifilum halophilum SMBg3 using the response surface methodology (RSM). Eight variables were screened to assess the effects of fermentation parameters on growth and metabolite production by Taguchi experimental design. Among these, the initial pH, temperature, and the percentage of MgSO4·7H2O in the medium were found to be most influential. The Box-Behnken design was applied to derive a statistical model for the optimization of these three fermentation parameters. The optimal parameters were initial pH: 8.3, temperature growth: 44°C, and MgSO4·7H2O: 1.6%, respectively. The maximum yield of biomass and metabolite production were, respectively, 11 mg/mL dry weight and 15.5 mm inhibition zone diameter against Salmonella enterica, which were in agreement with predicted values. The bioactive compounds were separated by the thick-layer chromatography technique and analyzed by GC/MS, NMR (1D and 2D), and Fourier-transform infrared spectroscopy (FT-IR). In addition to several fatty acids, N-(1-carboxy-ethyl)-phthalamic acid was identified as the main antibacterial compound. This element exhibited a potent activity against the ciprofloxacin-resistant Salmonella enterica CIP 8039 and Pseudomonas aeruginosa ATCC 9027 with a minimum inhibitory concentration (MIC) value range of 12.5-25 μg/mL. Results demonstrated that P. halophilum strain SMBg3 is a promising resource for novel antibacterial production due to its high-level yield potential and the capacity for large-scale fermentation.

[PMID: 31984886 DOI: 10.2174/1570179416666190306141318] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2018] [Revised: 12/28/2018] [Accepted: 02/04/2019] [Indexed: 01/29/2023]
Abstract
BACKGROUND Oxidative stress due to high levels of reactive organic species is the cause of the progression of inflammation in various diseases. The molecules possessing both anti-inflammatory and antioxidant activity can be the promising key to treat inflammatory diseases. Phthalimide and hydrazinecarbothioamide are anti-inflammatory and anti-oxidant pharmacophores. OBJECTIVE Molecular hybrids possessing above two pharmacophores were designed. A series of N-phenyl substituted 2-(2-(1,3-dioxoisoindolin-2-yl)acetyl)-N-phenylhydrazine-1-carbothioamide (CGS compounds) was synthesized and evaluated for biological activities. METHODS N-phthaloylglycyl hydrazide was reacted with unsubstituted/substituted phenyl isothiocyanates to yield CGS compounds. Synthesized compounds were evaluated for in vivo anti-inflammatory activity in carrageenan rat paw edema model, and in vitro anti-oxidant activity by DPPH assay. Levels of TNF-α and oxidative stress at the site of inflammation were measured. The genetic algorithm-PLS regression based QSAR model correlating the effect of N-phenyl substituent on the anti-inflammatory activity was developed. Further, the interaction of the active compound in the TNF-α binding pocket was studied by in silico docking. RESULTS Compound containing the 2-OCH3, 4-NO2 (CGS-5); 4-CF3 (CGS-9); 4-NO2 (CGS-3) showed significant anti-inflammatory activity (percentage inhibition of paw edema after 3 hour = 58.24, 50.38, 40.05, respectively) and potent anti-oxidant activity (IC50 =0.045, 0.998, 0.285 μg/ml, respectively). Reduced levels of TNF- α and increased levels of GSH were observed for the above three compounds. Descriptors for QSAR model identified by GA-PLS were WPSA1, Weta1unity, WDunity, SC3, VC5, MlogP, and WTPT3. The identified model was highly predictive, and value of root mean square error of prediction for internal (leave one out) and external validation was: 1.579, 1.325. CONCLUSION Molecular hybrids of phthalimide and hydrazinecarbothioamide were synthesized. Some of the compounds possessed promising anti-inflammatory and anti-oxidant activities.

Phthalimide Derivative Shows Anti-angiogenic Activity in a 3D Microfluidic Model and No Teratogenicity in Zebrafish Embryos. Front Pharmacol 2019; 10:349.

Abstract
Angiogenesis is a crucial event for tumor progression and metastasis. It is the process through which new blood vessels are formed and has become a therapeutic target in many cancer therapies. However, current anti-angiogenic drugs such as Thalidomide still have detrimental teratogenic effects. This property could be caused by the presence of chiral carbons, intrinsic to such compounds. We synthesized four different phthalimide derivatives that lack chiral carbons in their chemical structure. We hypothesized that these achiral carbon compounds would retain similar levels of anti-angiogenic activity whilst reducing teratogenic effects. We tested for their anti-angiogenic functions using an in vitro 3D microfluidic assay with human endothelial cells. All four compounds caused a drastic inhibition of angiogenesis at lower effective concentrations compared to Thalidomide. Quantification of the blood vessel sprouting in each condition allowed us to classify compounds depending on their anti-angiogenic capabilities. The most effective identified compound (C4), was tested in vivo on a zebrafish embryo model. Blood vessel development was measured using number and lengths of the stalks visible in the fli1a:EGFP transgenic line. Potential teratogenic effects of C4 were monitored over zebrafish embryonic development. The in vivo results confirmed the increased potency of C4 compared to Thalidomide demonstrated by results in embryos exposed to concentrations as low as 0.02 μM. The teratogenic analysis further validated the advantages of using C4 over Thalidomide in zebrafish embryos. This study highlights how the use of in vitro 3D model can allow rapid screening and selection of new and safer drugs.

Neuropharmacological Screening of Chiral and Non-chiral Phthalimide- Containing Compounds in Mice: in vivo and in silico Experiments. Med Chem 2019; 15:102-118.

Abstract
Background:
Thalidomide, the first synthesized phthalimide, has demonstrated sedative-
hypnotic and antiepileptic effects on the central nervous system. N-substituted phthalimides
have an interesting chemical structure that confers important biological properties.
Objective:
Non-chiral (ortho and para bis-isoindoline-1,3-dione, phthaloylglycine) and chiral
phthalimides (N-substituted with aspartate or glutamate) were synthesized and the sedative, anxiolytic
and anticonvulsant effects were tested.
Method:
Homology modeling and molecular docking were employed to predict recognition of the
analogues by hNMDA and mGlu receptors. The neuropharmacological activity was tested with the
open field test and elevated plus maze (EPM). The compounds were tested in mouse models of
acute convulsions induced either by pentylenetetrazol (PTZ; 90 mg/kg) or 4-aminopyridine (4-AP;
10 mg/kg).
Results:
The ortho and para non-chiral compounds at 562.3 and 316 mg/kg, respectively, decreased
locomotor activity. Contrarily, the chiral compounds produced excitatory effects. Increased
locomotor activity was found with S-TGLU and R-TGLU at 100, 316 and 562.3 mg/kg,
and S-TASP at 316 and 562.3 mg/kg. These molecules showed no activity in the EPM test or PTZ
model. In the 4-AP model, however, S-TGLU (237.1, 316 and 421.7 mg/kg) as well as S-TASP
and R-TASP (316 mg/kg) lowered the convulsive and death rate.
Conclusion:
The chiral compounds exhibited a non-competitive NMDAR antagonist profile and
the non-chiral molecules possessed selective sedative properties. The NMDAR exhibited stereoselectivity
for S-TGLU while it is not a preference for the aspartic derivatives. The results appear to
be supported by the in silico studies, which evidenced a high affinity of phthalimides for the
hNMDAR and mGluR type 1.

Abstract
1,2,4-Oxadiazoles and 4,5-dihydro-1,2,4-oxadiazoles are an interesting class of compounds because of their pharmacological and other properties. Although short descriptions of these compounds under mass spectrometric conditions exist, we thought it worthwhile to write a comprehensive review of this class of compounds. Therefore, this revision deals first with 1,2,4-oxadiazoles and then 4,5-dihydro-1,2,4-oxadiazoles from 1964 until the year 2002. Much work on these compounds has been described under electron impact conditions and only a little under chemical ionization (CI).

Abstract
The synthesis of six 3-aryl-5-(n-propyl)-4,5dihydro-1,2,4-oxadiazoles 3a-f has been achieved in a facile manner by the reaction of an appropriate arylamidoxime 1a-f with butyraldehyde 2. Oxidation of 3a-f individually using MnO(2) in CH(2)Cl(2) or sodium hypochlorite in THF/H(2)O furnished 1,2,4-oxadiazoles 4a-f in good to excellent yields. Compounds 4a-f were also evaluated against inflammation. Except 4e, all of them reduced inflammation, however, 4c presented better antiinflammatory activity. A preliminary antimicrobial activity tests of 3a-f showed that these compounds possess activity against some microorganisms. In fact, 3c and 3f have been found to be more effective against Staphylococcus aureus, Mycobacterium smegmatis, and Candida albicans.

Abstract
Some novel ester imides synthesised from trimellitic acid anhydride and 1-adamantanol or 2-adamantanol, were tested as antimicrobial compounds. Unfortunately, these agents showed a modest antibacterial activity (MIC > 6 microg/ml). However, a comparison of these N-substituted adamantylester imides with the series published previously, indicated that the incorporation of L-alanine and L-phenylalanine into the phthalimide moiety was the best choice regardless of the series and leads to antimicrobial activity against Staphylococcus aureus strains.

Abstract
A series of substituted N-arylphthalamic acids 3a-i has been synthesized by the reaction of phthalic anhydride 1 and aryl- or heterocyclic amines 2a-i, in the absence of solvents, in a domestic microwave oven. The formation of nine N-arylphthalamic acids was accomplished in 1-3 min giving excellent yields for compounds 3a-g, but moderate yield of compounds 3h and 3i, respectively. Compounds 3h and 3i are new. Interestingly, N-arylphthalamic acids 3a-i induced hyperlipidemia in Swiss white mice and also increased animals' body weight.
