7-oxo Staurosporine is an antibiotic originally isolated from S. platensis with diverse biological activites. It inhibits PKC, PKA, phosphorylase kinase, EGFR, and c-Src in vitro (IC50s = 9, 26, 5, 200, and 800 nM, respectively). 7-oxo Staurosporine induces cell cycle arrest in the G2/M phase in human leukemia K562 cells with a minimal effective dose (MED) of 30 ng/ml. It is cytotoxic to P388 mouse leukemia cells that are resistant and susceptible to doxorubicin . 7-oxo Staurosporine inhibits growth of the mycelial, but not yeast form of C. albicans, C. krusei, C. tropicalis, and C. lusitaniae (MICs = 3.1-25 μg/ml). It increases sphingomyelin synthesis in CHO-K1 cells when used at a concentration of 50 nM.
IKD-8344 is a macrocyclic dilactone originally isolated from an actinomycete species and has diverse biological activities, including anticancer, antimicrobial, and anthelmintic properties.1,2,3 It is cytotoxic to L5178Y murine leukemia cells (IC50 = 0.54 ng/ml).1 IKD-8344 inhibits growth of the mycelial form of C. albicans (MIC = 6.25 μg/ml) and potentiates the activity of polymyxin B against the multidrug-resistant pathogenic bacterium B. cenocepacia.2,3 It is active against T. spiralis in vitro and in vivo.1

Triclopyricarb (SYP-7017) is a strobilurin fungicide that can be used in crops disease control. Triclopyricarb inhibits mycelial growth with EC 50 values ranged from 0.006 μg/mL to 0.047 μg/mL.
Pyraziflumid is a fungicide. Pyraziflumid is a novel member of succinate dehydrogenase inhibitor fungicides (SDHI). The average EC50 value was 0.0561 (±0.0263)μg/ml for mycelial growth. There was no cross-resistance between pyraziflumid and the widely used fungicides carbendazim, dimethachlon and the phenylpyrrole fungicide fludioxonil.
Triclopyricarb (Standard) is the standard substance of Triclopyricarb, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. Triclopyricarb (SYP-7017), a strobilurin fungicide, is effective in controlling crop diseases by inhibiting mycelial growth, exhibiting EC 50 values ranging from 0.006 μg/mL to 0.047 μg/mL.
