Antibiotics

Inactone is a bioactive molecule of 3-glutarimidyl group that inhibits large ribosomal subunit.

It is produced by the strain of Str. sp. B 8300. Beta-Indomycinone has weak activity of anti-gram positive and negative bacteria and candida albicans, it also has antioxidant activity.

Inosamycin A is a broad-spectrum antimicrobial antibiotic originally isolated from Str. hygroscopicus No. J296-21. Its antibacterial activity was comparable to that of neomycin, and about twice that of ribomycin.

Inosamycin B is a broad-spectrum antimicrobial antibiotic originally isolated from Str. hygroscopicus No. J296-21. Its antibacterial activity is about half that of Inosamycin A.

Isariin B is originally isolated from Isaria felina.

It is produced by the strain of Str. griseus. Isocycloheximide has antifungal effect, and its activity to Barbiturates is only 30% of that of actinomyces.

It is produced by the strain of Actinoplanes philippinensis SANK 61681. Isohematinic acid has weak anti-anaerobic bacteria action.

Isosulfazecin is a beta-lactam antibiotic produced by the strain of Pseudomonas mesoacidophila sp. nov. Its anti-gram-positive bacteria effect is similar to SZ (Sulfazecin), but its anti-gram-negative bacteria activity is weaker than SZ.

Istamycin A is produced by the strain of Str. tenjimariensis S5-939. It has strong anti-gram positive and negative bacteria action, and Istamycin B has stronger antibacterial activity than A.

Istamycin B is produced by the strain of Str. tenjimariensis S5-939. It has strong anti-gram positive and negative bacteria action, and Istamycin B has stronger antibacterial activity than A.

It is produced by the strain of Janthinobacterium lividum. Janthinocin A has strong activity of anti-gram-positive bacteria and moderate anti-gram-negative bacteria, and has strong inhibitory effect on drug-resistant staphylococcus such as penicillin, tetracycline, erythromycin, methicillin and gentamicin.

Jietacin A is originally isolated from Str. sp. KP-197. It is found to be resistant to nematode, it can 100% kill Burs helenchus Lignicolus with the concentration of 0.25μg/mL, which is 10 times stronger than Avermectin B1a.

Juglomycin A is originally isolated from Str. distatochromogenes var. juglonensis 190-2. It has a broad spectrum of antibacterial and mycobacterial effects, and has the effect of inhibiting ehrlician ascites cancer in mice and prolongating life with 1 mg/kg.

It is produced by the strain of Micromono spora chalcea var. izumensis. Juvenimicin A2 can resist gram-positive bacteria and individual gram-negative bacteria.

Kalafungin is a quinone antibiotic produced by the strain of Str. tanashiensis Kala (NRRL 3215). It has anti-gram-positive bacterial and fungal effects as well as anti-parasite activity.

Kalimantacin A is originally isolated from Alcaligenes sp. YL-02632S. It has anti-Gram-positive bacteria (including multi-drug resistant bacteria) and some gram-negative bacteria activities.

Kanchanamycin C is originally isolated from Str. olivaceus TU4018. It has anti-gram positive and negative bacteria, yeast and filamentous fungus action.
