Abstract

In order to generate potent C-9154 antibiotic derivatives, it has been conducted the synthesis and antibacterial activity evaluation of p-anisyl ethyl fumarate and ethyl N-phenyl fumaramate. These target molecules were chosen as the former would be a para-methoxy substituted C-9154 derivative, whereas the latter would be an example of unsubstituted C-9154 derivative bearing an amido-ester fumaric side chain.p-Anisyl ethyl fumarate was synthesized from p-anisaldehyde by reduction with NaBH4, condensation of p-anisyl alcohol with maleic anhydride, and esterification of the resulting p-anisyl maleic acid with ethanol in the presence of benzenesulfonic acid as the catalyst. These reactions gave satisfactorily yields (55-81 %) in all steps involved. In the case of ethyl Nphenyl fumaramate, this molecule was synthesized in 84 % yield through condensation of aniline with maleic anhydride, followed by esterification with ethanol in the presence of concentrated sulfuric acid.The antibacterial activity test showed that the minimum inhibition concentration (MIC) of p-anisyl ethyl fumarate and ethyl N-phenyl fumaramate towards Staphyllococcus aureus were 15 and 25 μg/mL. Interestingly, the MIC values of these two compounds towards Eschericia coliwere also 15 and 25 μg/mL respectively. Thus, the data showed that the two C-9154 derivatives obtained are sufficiently potent and possess antibacterial activities which are comparable to the antibacterial activity of C-9154 itself towards Staphyllococcus aureus (12.5 – 37.5 μg/mL) and Eschericia coli (25 – 50 μg/mL).Key words: synthesis, antibacterial activity, fumarate and fumaramate.

Abstract

This research was conducted in order to synthesize two derivatives of C-9154 antibiotic from vanillin and to evaluate their biological activities. The synthesis of these C-9154 derivatives was performed through alkylation of vanillin, preparation of the corresponding benzaldoxim, reduction of this benzaldoxim, treatment of the resulting substituted benzilamine with maleic anhydride and esterification of this C-9154 antibiotic derivative. The alkylation of vanillin was carried out using diethylsulfate and NaOH as the base to give 89% yield of ethyl vanillin. The oxim synthesis from ethyl vanillin was performed using hydroxylamine hydrochloride under alkaline condition at 50oC for 2 hours to yield 89% 4-ethoxy-3-methoxybenzaldoxim. Reduction of this benzaldoxim with metallic Na in absolute ethanol afforded 82% yield of 4-ethoxy-3-methoxybenzylamine. This benzylamine derivative was then reacted with maleic anhydride in benzene to give the acid-form of C-9154 antibiotic derivative (6) in 74% yield. Esterification of this acid conducted Jumina using absolute ethanol in the presence of concentrated sulfuric acid at reflux for 4 hours gave the ethyl ester-form of C-9154 antibiotic derivative (7) in 87% yield. Antimicrobial activity evaluation was conducted using Staphyllococcus aureus and Eschericia coli. Based on the minimum inhibition concentration (MIC) data determined using aqueous methanol as the reference, it was observed that the acid-form (6) and the ethyl ester-form (7) of C-9154 antibiotic derivative obtained respectively gave MIC values of 2000-3000 g/ml and 500-1000 g/ml respectively either towards Staphyllococcus aureus or Eschericia coli.Key words: antibiotics, vanillin, oxim, benzylamine, C-9154 derivative, antimicrobe.

Abstract

This research was conducted in order to synthesize and investigate the antimicrobial activity of ethyl salicyl fumarate and ethyl furfuryl fumarate. These two target molecules were chosen as the former is the derivative of C-9154 antibiotic containing phenolic hydroxyl group, whereas the latter is an example of C-9154 antibiotic derivative bearing furan ring instead of benzene.Ethyl salicyl fumarate was synthesized from methyl salicylate through reduction with LiAlH4, condensation of salicyl alcohol with maleic anhydride, and esterification of salicyl maleic acid with ethanol in the presence of benzenesulfonic acid as the catalyst. These reactions gave satisfactory yields (76-92 %) in all steps involved. Similar to this procedure, ethyl furfuryl fumarate was prepared from furfural through reduction with NaBH4 followed by condensation of the resulted furfuryl alcohol with maleic anhydride and esterification of furfuryl maleic acid with ethanol in the presence of benzenesulfonic acid. Although the reduction of furfural and the condensation of furfuryl alcohol with maleic anhydride could be performed smoothly, the esterification of furfuryl maleic acid with ethanol only gave 38 % yield of ethyl furfuryl fumarate.The results of antimicrobial activity test showed that the value of minimum inhibition concentration (MIC) of salicyl maleic acid and ethyl salicyl fumarate towards Staphyllococcus aureus were 500 and 100 μg/mL, whereas towards Eschericia coli were 2000 and 4000 μg/mL respectively. In contrast, the MIC values of furfuryl maleic acid and ethyl furfuryl fumarate towards Staphyllococcus aureus and Eschericia coli were 150 and 100 μg/mL respectively.Keywords: synthesis, activity, C-9154 antibiotic, fumarate

Abstract

Absorpsi obat dapat terjadi dan dapat ditentukan dengan beberapa cara yaitu metode in vitro, metode in situ, dan metode in vivo. Absorpsi in situ melalui usus halus didasarkan atas penentuan jumlah hilangnya obat dari lumen usus halus. Penelitian ini bertujuan untuk mengetahui pengaruh PEG 400 sebagai surfaktan terhadap absorpsi piroksikam secara in situ. Uji kecepatan absorpsi piroksikam secara in situ oleh pengaruh penambahan PEG 400 dilakukan dengan menggunakan tiga macam larutan piroksikam dengan penambahan surfaktan PEG 400 1,0%, 1,5%, dan 2,0%. Larutan dimasukkan ke dalam lumen usus halus tikus jantan dengan berat 130-180 gram yang sudah dipuasakan (kira-kira 24 jam) dan dianestesi dengan uretan 40% b/v secara subkutan sebanyak 5.10-3 mL/g berat badan tikus. Cairan yang melewati usus halus ditampung dengan volume tertentu dan interval waktu tertentu. Kadar obat dalam larutan ditentukan secara spektrofotometri dengan panjang gelombang maksimal 353 nm kemudian dihitung Papp (tetapan permeabilitas semu). Data yang didapat diuji dengan analisis variansi satu jalan dan diteruskan dengan uji t jika terdapat perbedaan yang bermakna (taraf kepercayaan 95%). Hasil penelitian menunjukkan bahwa absorpsi piroksikam dengan penambahan PEG 400 secara in situ pada usus tikus putih jantan mengalami sedikit penurunan pada konsentrasi 1,5% kemudian meningkat pada konsentrasi 2,0%. Menurut hasil analisis variansi satu jalan, absorpsi tersebut menunjukkan hasil yang tidak berbeda secara statistik.
