Rifamycin B

The rifamycins are antibiotics derived from Streptomyces mediterranei.1 Their chemical structure is novel, with a long aliphatic bridge spanning an aromatic system. They act by inhibiting bacterial RNA polymerase, as do the actinomycins. Of the five compounds originally isolated, only rifamycin B was obtained in stable crystalline form, and three substances derived from this have come into clinical use: rifamycin SV, 2 rifampicin,3 and rifamycin B-diethylamide or rifamide (Rifocin-M - Lepetit).4

Substitution Reactions

[18]Annulene 1,4:7,10-dioxide-13,16-sulphide has been synthesized. The physical properties indicate that this compound is an aromatic system in which there is significant delocalization of the peripheral electrons. However, the compound undergoes addition rather than substitution reactions and therefore exhibits only limited classical aromaticity.

COFIRE merupakan upaya dalam mengurangi limbah sabut kelapa dengan memanfaatkannya menjadi bantal edukasi berbasis kebudayaan dengan menggunakan kain batik ciprat hasil karya anak disabilitas sebagai pelapis bantal dan pemberian aroma terapi olahan tanaman Lavender. Yogyakarta merupakan salah satu kawasan yang kaya akan potensi perkebunan kelapa. Masyarakat Yogyakarta dapat meningkatkan kesejahteraan melalui bisnis ini. Pemanfaatan sabut kelapa salah satunya dapat dijadikan sebagai pengganti penggunaan dacron dan kapuk berlebih pada isi bantal. Dacron dan kapuk berlebih memiliki dampak negatif bagi kesehatan manusia. Disisi lain, bantal aromaterapi dapat mengurangi tingkat insomnia pada masyarakat. Aroma terapi dihasilkan dari tanaman Lavender yang telah melalui proses destilasi uap dan kromatografi gas sehingga akan menghsilkan minyak astiri Lavender. Aromaterapi diberikan pada bahan utama yaitu sabut kelapa dan juga terdapat filter aromaterapi yang dapat diisi kembali ketika sudah habis sehingga pengguna dapat nyaman saat menggunakan bantal ini. Penjahitan produk sabut kelapa ini menggunakan socio entrepeneurship lulusan anak berkebutuhan khusus untuk meningkatkan pendapatan mereka secara finansial.

Universal Application

ABSTRACTMolecular imprinting leads to functional polymers that are capable to incorporate the template used and thus lead to selective chemical sensor systems when combined with a suitable transducer. Benzene and xylene can e.g. be distinguished with a selectivity factor of nearly ten using mass-sensitive devices such as QCM and SAW, although they both contain an aromatic system and differ only by the methyl groups. Sensing materials are further tuned by using binary mixtures as templates. When analyzing polycyclic aromatic hydrocarbons (PAH) by fluorescence and QCM measurements, the sensitivity is substantially increased if a second template molecule is applied as a porogen. Capacitive sensor measurements on polymers imprinted with microorganisms, such as yeasts, show substantial sensor responses due to highly selective inclusion compared with a non-functionalised surface yielding only negligible effects.
