Anidulafungin (LY303366) Image

Anidulafungin (LY303366)

CAS Number: 166663-25-8
Anidulafungin (LY303366) is a new semisynthetic echinocandin with antifungal potency. Anidulafungin (LY-303366) has MICs of ≤0.32 μg/mL for all Candida albicans (n=99), Candida glabrata (n=18), and Candida tropicalis (n=10) isolates tested. Anidulafungin is also active against Aspergillus species (minimum effective concentration at which 90% of the isolates are inhibited, 0.02 μg/mL) (n=20), is less active against Candida parapsilosis (MIC at which 90% of the isolates are inhibited [MIC90], 5.12 μg/mL) (n=10), and is inactive against C. neoformans (MIC90 >10.24 μg/mL) (n=15) and B. dermatitidis (MIC90, 16 μg/mL) (n=29).The MICs of Fluconazole for three strains of C. tropicalis, seven strains of C. glabrata, and two strains of Candida krusei are ≥16 μg/mL. The MICs of Anidulafungin for 11 of these 12 strains range from 0.08 to 0.32 mg/mL. The twelfth strain is a C. krusei strain (Fluconazole MIC, 32 μg/mL) for which the Anidulafungin MIC is 1.28 mg/mL. The MIC at which 90% of the isolates are inhibited (MIC90) for these 12 strains is 0.32 μg/mL. The Anidulafungin MIC90 for the remaining 18 C. glabrata isolates and C. tropicalis isolates for which the Fluconazole MICs are ≥ 8 μg/mL is also 0.32 mg/mL. Anidulafungin appeares equally active against Candida species for which the fluconazole MICs are ≥16 mg/mL and against those for which the fluconazole MICs are ≥ 8 μg/mL. Anidulafungin has significantly less activity against C. neoformans and B. dermatitidis than against C. albicans, C. glabrata, and C. tropicalis. Ketoconazole and amphotericin B are the most active antifungal agents tested for both C. neoformans and B. dermatitidis. Anidulafungin demonstrated potent in vitro activity against Aspergillus species with a MEC90 of 0.02 μg/mL. MICs of Anidulafungin for the control strain yeast isolates are 0.02 μg/mL for C. albicans ATCC 90028, 0.16 mg/mL for C. glabrata ATCC 90030, and >10.24 μg/mL for C. neoformans ATCC 90112[1]. Strains selected with CD101 that have a 2-fold or greater CD101 MIC increase also have at least a 2-fold MIC increase for Anidulafungin (ANF) and/or Caspofungin (CSF)[2].

Micafungin sodium Image

Micafungin sodium

CAS Number: 208538-73-2
Micafungin sodium is an inhibitor of 1, 3-beta-D-glucan synthesis, and used as an antifungal drug. Micafungin (10 mg/mL) phenotypicly decreases the formation of biofilm in most of the isolates. For all the genes tested, the levels of mRNA transcription are also decreased significantly in micafungin-treated samples cf. their untreated counterparts[1]. The combination of micafungin and KB425796-C is fungicidal and markedly reduces the number of CFU, in contrast to the fungistatic effects (no reduction in CFU) observed at all examined time points when each drug is used alone[2]. Micafungin (1 mg/kg) significantly prolongs survival compared with mice administered saline. Animals given a combination of micafungin (0.1 mg/kg) and KB425796-C (32 mg/kg) show a trend towards prolonged survival in comparison with those treated with micafungin (0.1 mg/kg) alone. In the livers of micafungin-treated mice, the number of CFUs decreases, although the clearance effect is less than that found in the kidneys. Combination treatment with micafungin and KB425796-C results in a significant decrease in the number of CFUs compared with the treatment with micafungin alone at all examined doses. The clearance effect associated with KB425796-C in combination with micafungin is greater than that observed in AMPH-treated animals[2].
Micafungin FR-179642 impurity acid Image

Caspofungin acetate Image

Caspofungin acetate

CAS Number: 179463-17-3
Caspofungin acetate is an lipopeptide antifungal β-1,3-glucan synthase inhibitor. Mice injected with caspofungin at vitreal concentrations from 0.41 to 4.1 μM do not have significant alterations in their ERG waveforms, and their retinas have no detectable morphologic changes or loss of cells. At the vitreal concentration of 41 μM, caspofungin reduces the amplitudes of the a-waves, b-waves, and scotopic threshold responses of the ERG and also produces a decrease in the number of cells in the ganglion cell layer[1]. Caspofungin (8 mg/kg) or amphotericin B at 1 mg/kg given i.p. once daily for 7 days beginning at 30 h after infection resulted in 100% survival through day 28 relative to vehicle control treatment, which results in 100% mortality by day 11 after infectious challenge. Caspofungin reduces recovery of viable Candida from kidney and brain tissues compared to vehicle control treatment on day 5, when control burden peaked. Caspofungin-treated mice dosed with 2 mg/kg or greater have significantly lower brain burden than amphotericin-B-treated mice at day 5. Amphotericin B and caspofungin treatment reduce kidney fungal burden by 1.7 log CFU/g and 2.46 to 3.64 log CFU/g, respectively.

Afatinib dimaleate Image

Afatinib dimaleate

CAS Number: 850140-73-7
Afatinib dimaleate is an orally bioavailable dual receptor tyrosine kinase (RTK) inhibitor with potential antineoplastic activity. EGFR/HER2 tyrosine kinase inhibitor BIBW 2992 irreversibly binds to and inhibits human epidermal growth factor receptors 1 and 2 (EGFR-1; HER2), which may result in the inhibition of tumor growth and angiogenesis. EGFR/HER2 are RTKs that belong to the EGFR superfamily; both play major roles in tumor cell proliferation and tumor vascularization and are overexpressed in many cancer cell types. Afatinib is approved in much of the world (including the United States, Canada, the United Kingdom and Australia) for the treatment of metastatic non-small cell lung carcinoma (NSCLC), developed by Boehringer Ingelheim. It acts as an angiokinase inhibitor.

Lenvatinib is an orally active, multi-target inhibitor, mostly for VEGFR2(KDR)/VEGFR3(Flt-4) with IC50 of 4 nM/5.2 nM, and less potent against VEGFR1/Flt-1, and approximately 10-fold more selective for VEGFR2/3 against FGFR1, PDGFRα/β.
Lenvatinib mesylate Image

Lenvatinib mesylate

CAS Number: 857890-39-2
Lenvatinib, also known as E7080, is a synthetic, orally available inhibitor of vascular endothelial growth factor receptor 2 (VEGFR2, also known as KDR/FLK-1) tyrosine kinase with potential antineoplastic activity. E7080 blocks VEGFR2 activation by VEGF, resulting in inhibition of the VEGF receptor signal transduction pathway, decreased vascular endothelial cell migration and proliferation, and vascular endothelial cell apoptosis.
