Abstract
In this innovative research, a novel series of thiazolidin-4-one analogues having a 1,3,4-oxadiazole/thiadiazole moiety were derived and the structures of all the newly obtained molecules were established using different physicochemical and analytical means (1H-NMR, FTIR, mass spectra, and elemental analyses). The synthesized molecules were then investigated for their antiproliferative, antimicrobial, and antioxidant potential. The cytotoxicity screening studies revealed that analogues D-1, D-6, D-15, and D-16 possessed comparable efficacy, within the IC50 range (1 to 7 μM), when taking doxorubicin as a reference drug (IC50 = 0.5 μM). The antimicrobial activity was assessed using different Gram-(+) and Gram-(-) bacterial and fungal strains and the results revealed that molecules D-2, D-4, D-6, D-19, and D-20 possessed potent activity against selective strains of microbes with MIC ranges of 3.58 to 8.74 µM. The antioxidant evaluation was performed using the DPPH assay and the screening results revealed that analogue D-16 was the most potent derivative (IC50 = 22.3 µM) when compared with the positive control, ascorbic acid (IC50 = 111.6 µM). Structure-activity relationship (SAR) studies of the synthesized novel derivatives revealed that para-substituted halogen and hydroxy derivatives have remarkable potential against the MCF-7 cancer cell line and antioxidant potential. Similarly, electron-withdrawing groups (Cl/NO2) and -donating groups at the para position possess moderate to promising antimicrobial potential.

Abstract
By exploiting the ample biological potential of 1,3,4-oxadiazole/thiadiazole ring, 4-substitutedphenyl-1,3,4-oxadiazol/Thiadiazol-2-yl)-4-(4-substitutedphenyl) azetidin-2-one derivatives were prepared. Various substituted azetidin-2-one derivatives have been identified as immunostimulating and antimicrobial, as well as their antioxidant activity. 2-amino 1,3,4 oxadiazole/thiadiazole conjugates were synthesized by mixing semi/thio carbazides and sodium acetate with water and stirring well, followed by adding aldehydes in methanol at room temperature. Acetate (glacial) was used as the catalyst to produce Schiff’s bases (intermediates) by treating substituted aldehydes with 2-amino 1,3,4 oxadiazole/thiadiazole(s). Using the mixture of triethylamine (dropwise) and chloroacetylchloride with vigorous stirring, 4-substitutedphenyl-1,3,4-oxadiazol/Thiadiazol-2-yl)-4-(4-substitutedphenyl) azetidin-2-one derivatives were prepared. The newly synthesized conjugates were evaluated for their anticancer potential using MCF-7 cell lines. Amoxicillin and fluconazole were used as reference drugs to determine their antimicrobial activity. Synthesized derivatives were evaluated for their antioxidant properties using 2-diphenyl-1-picrylhydrazyl (DPPH). In vitro cytotoxicity screening (MTTS assay) revealed that derivatives AZ-5, 9, 10, 14 and 19 demonstrated high efficacy with the percentage of inhibition at different concentration ranges (0.1 μM, 0.5 μM, 1 μM, 2 μM) of 89% to 94% μM as compared to doxorubicin as standard drug. The antimicrobial study indicated that compounds AZ-10, 19, and AZ-20 were found to have significant antimicrobial potential with MIC ranges of 3.34 µM to 3.71 µM in comparison to reference drugs having 4.29 µM to 5.10 µM. Based on antioxidant screening, most of the synthetic derivatives showed greater stability and effectiveness than the standard drug. According to the antioxidant screening, compounds AZ-5 and AZ-15 (IC50 = 45.02 μg/mL and 42.88 μg/mL, respectively) showed the greatest potency, as compared to ascorbic acid (IC50 = 78.63 μg/mL). Structure-activity relationship (SAR) studies of synthesized novel derivatives revealed that para-substituted halogen and nitro derivatives have remarkable potential against MCF-7 cancer cell lines and different microbial strains. Current evidence indicates that the synthesized derivatives may be promising candidates for use in the prevention and treatment of these infections. These synthesized compounds require further mechanism-based research to understand how they interact with the cells.

Bioorg Chem 2022; 129:106186.

Abstract
Antimicrobial resistance (AMR) is one of the critical challenges that have been encountered over the past years. On the other hand, bacterial DNA gyrase is regarded as one of the most outstanding biological targets that quinolones can extensively inhibit, improving AMR. Hence, a novel series of 3-(7-nitro-3-oxo-3,4-dihydroquinoxalin-2-yl)propanehydrazide derivatives (3-6j) were designed and synthesized employing the quinoxaline-2-one scaffold and relying on the pharmacophoric features experienced by the quinolone antibiotic; ciprofloxacin. The antibacterial activity of the synthesized compounds was assessed via in-vitro approaches using eight different Gram-positive and Gram-negative bacterial species. Most of the synthesized compounds revealed eligible antibacterial activities. In particular, compounds 6d and 6e displayed promising antibacterial activity among the investigated compounds. For example, compounds 6d and 6e displayed MIC values of 9.40 and 9.00 µM, respectively, regarding S. aureus, and 4.70 and 4.50 µM, respectively, regarding S. pneumonia in comparison to ciprofloxacin (12.07 µM). The cytotoxicity of compounds 6d and 6e were performed on normal human WI-38 cell lines with IC50 values of 288.69 and 227.64 μM, respectively assuring their safety and selectivity. Besides, DNA gyrase inhibition assay of compounds 6d and 6e was carried out in comparison to ciprofloxacin, and interestingly, compounds 6d and 6e disclosed promising IC50 values of 0.242 and 0.177 μM, respectively, whereas ciprofloxacin displayed an IC50 value of 0.768 μM, assuring the proposed mechanism of action for the afforded compounds. Consequently, compounds 6d and 6e were further assessed via in-vivo approaches by evaluating blood counts, liver and kidney functions, and histopathological examination. Both compounds were found to be safer on the liver and kidney than the reference ciprofloxacin. Moreover, in-silico molecular docking studies were established and revealed reasonable binding affinities for all afforded compounds, particularly compound 6d which exhibited a binding score of -7.51 kcal/mol, surpassing the reference ciprofloxacin (-7.29 kcal/mol) with better anticipated stability at the DNA gyrase binding pocket. Moreover, ADME studies were conducted, disclosing an eligible bioavailability score of >0.55 for all afforded compounds, and reasonable GIT absorption without passing the blood brain barrier was attained for most investigated compounds, ensuring their efficacy and safety. Lastly, a structure activity relationship study for the synthesized compounds was established and unveiled that not only the main pharmacophores required for DNA gyrase inhibition are enough for exerting promising antimicrobial activities, but also derivatization with diverse aryl/hetero aryl aldehydes is essential for their enhanced antimicrobial potential.

Abstract
Herein we describe the synthesis of a series of nickel(II) complexes (C1–C3) with Schiff bases (HL1–HL3) derived from 4-amino-5-mercapto-3-methyl-1,2,4-triazole and ortho/meta/para-nitrobenzaldehyde having composition [Ni(L)2(H2O)2]. The obtained ligands and their complexes were characterized using physico-chemical techniques viz., elemental analysis, magnetic moment study, spectral (electronic, FT-IR, 1H-NMR) and thermal analysis. The elemental analysis and spectral analysis revealed that Schiff bases behave as monoanionic bidentate ligands towards the Ni(II) ion. Whereas, the magnetic moment study suggested the octahedral geometry of all the Ni(II) complexes. The thermal behavior of the complexes has been studied by thermogravimetric analysis and agrees well with the composition of complexes. Further, the biological activities such as antimicrobial and antifungal studies of the Schiff bases and Ni(II) complexes have been screened against bacterial species (Staphylococcus aureus and Pseudomonas aeruginosa) and fungal species (Aspergillus niger and Candida albicans) activity by MIC method, the results of which revealed that metal complexes exhibited significant antimicrobial activities than their respective ligands against the tested microbial species. Furthermore, the molecular docking technique was employed to investigate the active sites of the selected protein, which indeed helped us to screen the potential anticancer agents among the synthesized ligand and complexes. Further, these compounds have been screened for their in vitro anticancer activity using OVCAR-3 cell line. The results revealed that the complexes are more active than the ligands.

Abstract
:
To overcome the upsurge of antimicrobial resistance that has emerged in recent years,
there is a need for the development of newer hits having satisfying anti-infective activity. Hydrazides
incorporated with an azomethine hydrogen account for a cardinal class of molecules for the
development of newer derivatives. Hydrazide derivatives have gained considerable interest of medicinal
chemists owing to their diverse bioactivity. In the present review, we have attempted to
compile the recent trends in the synthesis of hydrazides and their substituted derivatives. The structural
features that lead to the desired antimicrobial activity are highlighted, which will lead the way
for synthetic and medicinal chemists to focus on newer designs in this arena.

Abstract
Pantothenamides (PanAms) are potent antiplasmodials with low human toxicity currently being investigated as antimalarials with a novel mode of action. These structural analogues of pantothenate, the vitamin precursor of the essential cofactor coenzyme A, are susceptible to degradation by pantetheinase enzymes present in serum. We previously discovered that α-methylation of the β-alanine moiety of PanAms increases their stability in serum and identified N-phenethyl-α-methyl-pantothenamide as a pantetheinase-resistant PanAm with potent, on-target, and selective antiplasmodial activity. In this study, we performed structure-activity relationship investigations to establish whether stability and potency can be improved further through alternative modification of the scissile amide bond and through substitution/modification of the phenyl ring. Additionally, for the first time, the importance of the stereochemistry of the α-methyl group was evaluated in terms of stability versus potency. Our results demonstrate that α-methylation remains the superior choice for amide modification, and that while monofluoro-substitution of the phenyl ring (that often improves ADME properties) was tolerated, N-phenethyl-α-methyl-pantothenamide remains the most potent analogue. We show that the 2S,2'R-diastereomer is far more potent than the 2R,2'R-diastereomer and that this cannot be attributed to preferential metabolic activation by pantothenate kinase, the first enzyme of the coenzyme A biosynthesis pathway. Unexpectedly, the more potent 2S,2'R-diastereomer is also more prone to pantetheinase-mediated degradation. Finally, the results of in vitro studies to assess permeability and metabolic stability of the 2S,2'R-diastereomer suggested species-dependent degradation via amide hydrolysis. Our study provides important information for the continued development of PanAm-based antimalarials.

Synthesis and Structure Insights of Two Novel Broad-Spectrum Antibacterial Candidates Based on ( E)- N'-[(Heteroaryl)methylene]adamantane-1-carbohydrazides. Molecules 2020; 25:molecules25081934.

Abstract
Two new N′-heteroarylidene-1-carbohydrazide derivatives, namely; E-N′-[(pyridine-3-yl)methylidene]adamantane-1-carbohydrazide (1) and E-N′-[(5-nitrothiophen-2-yl)methylidene]adamantane-1-carbohydrazide (2), were produced via condensation of adamantane-1-carbohydrazide with the appropriate heterocyclic aldehyde. Both compounds were chemically and structurally characterized by 1H-NMR, 13C-NMR, infrared and UV-vis spectroscopies, and single crystal X-ray diffraction. The study was complemented with density functional theory calculations (DFT). The results show an asymmetrical charge distribution in both compounds, with the electron density accumulated around the nitrogen and oxygen atoms, leaving the positive charge surrounding the N-H and C-H bonds in the hydrazine group. Consequently, the molecules stack in an antiparallel fashion in the crystalline state, although the contribution of the polar contacts to the stability of the lattice is different for 1 (18%) and 2 (42%). This difference affects the density and symmetry of their crystal structures. Both molecules show intense UV-Vis light absorption in the range 200–350 nm (1) and 200–500 nm (2), brought about by π → π* electronic transitions. The electron density difference maps (EDDM) revealed that during light absorption, the electron density flows within the π-delocalized system, among the pyridyl/thiophene ring, the nitro group, and the N′-methyleneacetohydrazide moiety. Interestingly, compounds 1 and 2 constitute broad-spectrum antibacterial candidates, displaying potent antibacterial activity with minimal inhibitory concentration (MIC) values around 0.5–2.0 μg/mL. They also show weak or moderate antifungal activity against the yeast-like pathogenic fungus Candida albicans.

Abstract
Background:
Acquired immunodeficiency syndrome (AIDS) and cancer treatment have been
a major task for research scientists and pharmaceutical industry for the last many years. Seeking to the
development, many promising chemical entities especially five-membered heterocyclic rings like oxadiazole
have revealed good anticancer and anti HIV activities. The current review enlists some recently
developed anti-HIV and anti-cancer oxadiazole moieties.
Methods:
on the basis of structural modification for the syntheses of new oxadiazole analogs, the new
anti-HIV and anti-cancer agents have been summarized, which can improve treatment of AIDs and cancer.
Results:
The oxadiazole ring is more potent in comparison to some other heterocyclic rings (five and
six membered) towards anti-HIV and anti-cancer activities. The important mechanisms involved for anti
HIV and anticancer activity are mainly inhibition of enzymes like protease, HIV-integrase, telomerase,
histone deacetylase, methionine amino peptidase, thymidylate synthase and focal adhesion kinase and
inhibition of some growth factors.
Conclusion:
By reviving the past literature about 50 most potent oxadiazole derivatives, depending
upon activity and structural modifications, have been selected as potent anti-HIV, and anti-cancer
agents. Thus, oxadiazole seems to be a ‘privileged structure’ for further screening and syntheses of the
new drug analogs against life threatening HIV and cancer like diseases.

Abstract
Pantothenamides (PanAms) are analogues of pantothenate, the biosynthetic precursor of coenzyme A (CoA), and show potent antimicrobial activity against several bacteria and the malaria parasite in vitro. However, pantetheinase enzymes that normally degrade pantetheine in human serum also act on the PanAms, thereby reducing their potency. In this study, we designed analogues of the known antibacterial PanAm N-heptylpantothenamide (N7-Pan) to be resistant to pantetheinase by using three complementary structural modification strategies. We show that, while two of these are effective in imparting resistance, the introduced modifications have an impact on the analogues' interaction with pantothenate kinase (PanK, the first CoA biosynthetic enzyme), which acts as a metabolic activator and/or target of the PanAms. This, in turn, directly affects their mode of action. Importantly, we discover that the phosphorylated version of N7-Pan shows pantetheinase resistance and antistaphylococcal activity, providing a lead for future studies in the ongoing search of PanAm analogues that show in vivo efficacy.

Abstract
The design, synthesis and biological evaluation of a library of 1,2,3-triazole carboxylates incorporating carboxylic acid, hydroxymethyl, carboxylic acid hydrazide, carboxamide and benzenesulfonamide moieties is disclosed. All the novel compounds were investigated for their inhibition potential against carbonic anhydrase (CA, EC 4.2.1.1) human (h) isoforms hCA I, II, IV and IX, well established drug targets. The cytosolic isoform hCA I was inhibited with Ki's ranging between 53.2 nM and 7.616 μM whereas the glaucoma associated cytosolic isoform hCA II was inhibited with Ki's in the range 21.8 nM-0.807 μM. The membrane bound isoform hCA IV, involved in glaucoma and retinitis pigmentosa among others, was effectively inhibited by some of these compounds with Ki < 60 nM, better than the reference drug acetazolamide (AAZ). The tumor associated isoform hCA IX, a recently validated antitumor/antimetastatic drug target, was also effectively inhibited by some of the new sulfonamides, which possess thus the potential to be used as tools for exploring in more details the selective inhibition of hCAs involved in various pathologies.

Abstract
Thirty new derivatives of palmitic acid were efficiently synthesized. All obtained compounds can be divided into three groups of derivatives: Thiosemicarbazides (compounds 1-10), 1,2,4-triazoles (compounds 1a-10a) and 1,3,4-thiadiazoles (compounds 1b-10b) moieties. ¹H-NMR, 13C-NMR and MS methods were used to confirm the structure of derivatives. All obtained compounds were tested in vitro against a number of microorganisms, including Gram-positive cocci, Gram-negative rods and Candida albicans. Compounds 4, 5, 6, 8 showed significant inhibition against C. albicans. The range of MIC values was 50-1.56 μg/mL. The halogen atom, especially at the 3rd position of the phenyl group was significantly important for antifungal activity. The biological activity against Candida albicans and selected molecular descriptors were used as a basis for QSAR models, that have been determined by means of multiple linear regression. The models have been validated by means of the Leave-One-Out Cross Validation. The obtained QSAR models were characterized by high determination coefficients and good prediction power.

Abstract
Some novel hydrazone derivatives 6a–o were synthesized from the key intermediate 4-Chloro-N-(2-hydrazinocarbonyl-phenyl)-benzamide 5 and characterized using IR, 1H-NMR, 13C-NMR, mass spectroscopy and elemental analysis. The inhibitory potential against two secretory phospholipase A2 (sPLA2), three protease enzymes and eleven bacterial strains were evaluated. The results revealed that all compounds showed preferential inhibition towards hGIIA isoform of sPLA2 rather than DrG-IB with compounds 6l and 6e being the most active. The tested compounds exhibited excellent antiprotease activity against proteinase K and protease from Bacillus sp. with compound 6l being the most active against both enzymes. Furthermore, the maximum zones of inhibition against bacterial growth were exhibited by compounds; 6a, 6m, and 6o against P. aeruginosa; 6a, 6b, 6d, 6f, 6l, 6m, 6n, and 6o against Serratia; 6k against S. mutans; and compounds 6a, 6d, 6e, 6m, and 6n against E. feacalis. The docking simulations of hydrazones 6a–o with GIIA sPLA2, proteinase K and hydrazones 6a–e with glutamine-fructose-6-phosphate transaminase were performed to obtain information regarding the mechanism of action.

Abstract
A series of 4-(1-aryl-2-oxo-1,2-dihydro-indol-3-ylideneamino)-N-substituted benzenesulfonamide derivatives (1-32) was synthesized and evaluated for its in vitro antimicrobial, antiviral and cytotoxic activities. Antimicrobial results indicated that compounds (11) and (18) were found to be the most effective ones. In general, the synthesized compounds were bacteriostatic and fungistatic in their action. The cytotoxic screening results indicated that the compounds were less active than the standard drug 5-fluorouracil (5-FU). None of the compounds inhibited viral replication at subtoxic concentrations. In general, the presence of a pyrimidine ring with electron releasing groups and an ortho- and para-substituted benzoyl moiety favored antimicrobial activities. The results of QSAR studies demonstrated the importance of topological parameters, valence zero order molecular connectivity index (0χv) and valence first order molecular connectivity index (1χv) in describing the antimicrobial activity of synthesized compounds.

Abstract
Three novel thiosemicarbazone O-carboxymethyl chitosan derivatives were obtained via a condensation reaction of thiosemicarbazide O-carboxymethyl chitosan with o-hydroxybenzaldehyde, p-methoxybenzaldehyde, and p- chlorobenzaldehyde respectively. Their structures were characterized by elemental analysis, FTIR, (13)C NMR and X-ray diffraction. The antimicrobial behaviors of the prepared derivatives against three types of bacteria Staphylococcus aureus (S. aureus, RCMBA 2004), Bacillus subtilis (B. subtilis, RCMBA 6005), and Escherichia coli (E. Coli, RCMBA 5003) and three crops-threatening pathogenic fungi Aspergillus fumigatus (A. fumigatus, RCMBA 06002), Geotrichum candidum (G. candidum, RCMB 05098), and Candida albicans (C. albicans, RCMB 05035) were investigated. The results indicated that the antibacterial and antifungal activities of the investigated derivatives are much higher than those of the parent O-carboxymethyl chitosan. They were more potent in case of Gram-positive bacteria than Gram-negative bacteria. The presence of electron withdrawing chlorine atom on the aryl moiety of the aldehyde portion improved greatly antimicrobial activity to be nearly equivalent to the used standard drugs.

[PMID: 24198736 PMCID: PMC3808720 DOI: 10.1155/2013/981764] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2013] [Revised: 08/14/2013] [Accepted: 08/15/2013] [Indexed: 11/17/2022] Open
Abstract
An EtOH solution of 3-ketobutanehydrazide and salicylhydrazide on refluxing in equimolar ratio forms the corresponding Schiff base, LH3 (1). The latter reacts with Mn(II), Co(II), Ni(II), Cu(II), Zn(II), Cd(II), Zr(OH)2(IV), MoO2(VI), and UO2(VI) ions in equimolar ratio and forms the corresponding coordination compounds, [M(LH)(MeOH)3] (2, M = Mn, Co, Ni), [Cu(LH)]2 (3), [M′(LH)(MeOH)] (4, M′ = Zn, Cd), [Zr(OH)2(LH)(MeOH)2] (5), [MoO2(LH)(MeOH)] (6), and [UO2(LH)(MeOH)] (7). The coordination compounds have been characterized on the basis of elemental analyses, molar conductance, spectral (IR, reflectance, 1H NMR, ESR) studies, and magnetic susceptibility measurements. They are nonelectrolytes in DMSO. The coordination compounds, except 3, are monomers in diphenyl. They are active against gram-positive bacteria (S. aureus, B. subtilis), gram-negative bacteria (E. coli, P. aeruginosa), and yeast (S. cerevisiae, C. albicans). 1 acts as a dibasic tridentate ONO donor ligand in 2–7 coordinating through its both enolic O and azomethine N atoms. The coordination compounds 2 and 3 are paramagnetic, while rest of the compounds are diamagnetic. A square-planar structure to 3, a tetrahedral structure to 4, an octahedral structure to 2, 6, and 7, and a pentagonal bipyramidal structure to 5 are proposed.

Abstract
Abstract Various 5-substituted-2-(1-((diethylamino)methyl)-2-oxoindolin-3-ylidene)hydrazinecarbothioamide (4a, b) and 5-substituted-2-(1-((diethylamino)methyl)-2-oxoindolin-3-ylidene)-N-(phenyl-4-substituted)hydrazinecarbothioamide (5a–h) derivatives were synthesized. The compounds were screened for cytotoxicity against human HeLa and CEM T-lymphocytes as well as murine L1210 cells. The compounds were also screened for β-lactamase inhibitory activity, antiviral, antibacterial, and antifungal activity against various strains of microorganisms. Several of these compounds were endowed with low micromolar 50 %-cytostatic concentration (IC50) values, and some were virtually equally potent as melphalan. The most potent inhibitors against the murine leukemia cells (L1210) were also the most inhibitory against human T-lymphocyte (CEM) tumor cells. Derivative 2-(1-((diethylamino)methyl)-2-oxoindolin-3-ylidene)-N-(4-methoxyphenyl)hydrazinecarbothioamide 5c emerged as the most potent cytostatic compound among the tested compounds. Derivatives 4b, 5a, 5b, and 5d showed antiviral activity against HEL cell cultures (IC50 11–20 μM). Moderate antimicrobial activity was observed for all derivatives. The encouraging cytostatic and antiviral activity data provide an adequate rationale for further modification of these molecular scaffolds. Graphical abstract Derivative 5c (1.9–4.4 μM) emerged as the most potent cytostatic compound among the tested compounds. Derivatives 4b, 5a, 5b, and 5d showed antiviral activity against HEL cell cultures (IC50 11–20 μM). ![]()

Abstract
ABSTRACT A variety of N'-[4-[(substituted imino)methyl]benzylidene]-substituted benzohydrazides have been synthesized and evaluated for antimicrobial and anticancer potential. Results from testing of antimicrobial activity indicated the most potent antimicrobial agents had pMIC am = 1.51. The synthesized compounds were bacteriostatic and fungistatic in action. Results from evaluation of antiviral activity indicated that none of the synthesized hydrazide derivatives inhibited viral replication at sub-toxic concentrations. Results from anti-HIV screening against HIV-2 strain ROD indicated that one compound was more potent (IC 50 ≥ 1 μg/cm3) than the standard drug nevirapine (IC 50 ≥ 4 μg/cm3) and another was equipotent (IC 50 ≥ 4 μg/cm3). The most effective anticancer agent against both HCT116 and MCF7 cancer cell lines had IC 50 = 19 and 18 μg/cm3, respectively. QSAR analysis indicated the importance of Wiener index (W) and energy of the lowest unoccupied molecular orbital (LUMO) in describing the antimicrobial activity of the synthesized compounds.

Abstract
A series of new N-acylhydrazone derivatives were synthesized in good yields through the reactions of dehydroabietic acid hydrazide with a variety of substituted arylaldehydes. The structures of the synthesized compounds were confirmed by IR, 1H- and 13C-NMR, ESI-MS, elemental analysis and single crystal X-ray diffraction. From the crystal structure of compound 4l, the C=N double bonds of these N-acylhydrazones showed (E)-configuration, while the NMR data of compounds 4a-q indicated the existence of two rotamers for each compound in solution. The target compounds were evaluated for their antibacterial activities against four microbial strains. The result suggested that several compounds exhibited pronounced antibacterial activities. Particularly, compound 4p exhibited good antibacterial activity against Staphylococcus aureus and Bacillus subtilis comparable to positive control. The possible antibacterial metabolism and the strategy for further optimization of this compound were also discussed.
