7-epi-Clindamycin 2-phosphate
CAS:7-epi-Clindamycin 2-phosphate is a semisynthetic antibiotic derivative, which is sourced from chemical modifications of the natural antibiotic lincomycin. This compound operates by inhibiting bacterial protein synthesis. It achieves this by binding to the 50S subunit of the bacterial ribosome, thereby obstructing the translocation steps in protein elongation.Fórmula:C18H34ClN2O8PSPureza:Min. 95%Cor e Forma:White to off-white solid.Peso molecular:504.96 g/molSpiramycin I
CAS:Spiramycin I is a macrolide antibiotic with action on bacterial protein synthesis inhibition and is used for treating toxoplasmosis and bacterial infections.

CAS:Nocardamine is a siderophore-based antioxidant, which is naturally derived from the soil-dwelling actinobacteria known as Streptomyces. Its primary mode of action involves the chelation of metal ions, effectively sequestering them and preventing metal-catalyzed oxidation reactions. By binding to iron and other transition metals, Nocardamine mitigates oxidative stress at a cellular level, which could otherwise contribute to cellular damage and dysfunction.

CAS:Bleomycin A5 hydrochloride is an antineoplastic antibiotic, which is derived from the bacterium Streptomyces verticillus. Its mode of action involves binding to DNA and inducing strand breaks through the generation of free radicals, specifically targeting deoxyribose units. This leads to the inhibition of DNA synthesis and cell division, ultimately resulting in cell death.Fórmula:C57H89N19O21S2•HClPureza:Min. 95%Cor e Forma:PowderPeso molecular:1,177.03 g/molHygromycin A
CAS:Hygromycin A is an antimicrobial compound isolated from the bacterium *Streptomyces hygroscopicus*. It functions by inhibiting protein synthesis within microbial cells. This compound disrupts the elongation phase of translation by binding to the ribosomal subunit, therefore impeding mRNA decoding during protein assembly.Fórmula:C23H29NO12Pureza:Min. 95%Peso molecular:511.5 g/molMonensin
CAS:Monensin is a polyether ionophore antibiotic, which is derived from the fermentation of the bacterium *Streptomyces cinnamonensis*. It operates by disrupting ion transport across biological membranes, primarily by facilitating the exchange of sodium and potassium ions. This ionophore action alters the osmotic balance in target cells, leading to their destabilization and death, particularly in Gram-positive bacteria and certain protozoa.Fórmula:C36H62O11Pureza:Min. 95%Peso molecular:670.87 g/molSancycline hydrochloride
CAS:Sancycline hydrochloride is a tetracycline antibiotic, which is derived from the natural fermentation process of Streptomyces bacteria. The mechanism of action involves the inhibition of protein synthesis by bindin directly to the 30S ribosomal subunit, thereby preventing the attachment of aminoacyl-tRNA to the A site of the ribosome. This action effectively halts the growth of bacteria by impeding protein production, making it bacteriostatic rather than bactericidal.Fórmula:C21H23ClN2O7Pureza:Min. 95%Peso molecular:450.87 g/molAzidamfenicol
CAS:Azidamfenicol inhibits ribosomal peptidyltransferase with a Ki of 22 µM. Azidamfenicol is a broad-spectrum chloramphenicol-like antibiotic.

CAS:Clindamycin 3-phosphate is an antibiotic prodrug, which is a derivative of clindamycin. It is semisynthetic with a synthetic origin, derived by chemically modifying the natural compound lincomycin obtained from the bacterium *Streptomyces lincolnensis*. The mode of action of Clindamycin 3-phosphate involves the inhibition of bacterial protein synthesis. It binds to the 50S subunit of the bacterial ribosome, thereby interfering with the translocation step in protein elongation, ultimately leading to the suppression of bacterial growth.Fórmula:C18H34ClN2O8PSPureza:Min. 95%Cor e Forma:White To Off-White SolidPeso molecular:504.96 g/mol4-Demethyl daunomycinone
CAS:4-Demethyl daunomycinone is an anthracycline derivative, which is a natural or semi-synthetic compound derived from the bacterium *Streptomyces*. It is primarily studied for its potential use in anticancer therapies, given its structural similarity to other well-known anthracyclines like daunorubicin and doxorubicin. These compounds are known to intercalate into DNA, thereby disrupting the function of DNA and RNA synthesis, leading to the inhibition of cell proliferation.Fórmula:C20H16O8Pureza:Min. 95%Peso molecular:384.34 g/molCcpA-IN-1

CAS:S-Adenosylhomocysteine (SAH) hydrolase is responsible for the reversible hydrolysis of SAH into adenosine and homocysteine. Inhibition of this enzyme leads to the accumulation of SAH within cells, thereby increasing the SAH to S-adenosylmethionine (SAM) ratio and subsequently inhibiting SAM-dependent methyltransferases. (−)-Neplanocin A, a potent and irreversible inhibitor of SAH hydrolase (Ki= 8.39 nM), exhibits significant antitumor activity against mouse leukemia L1210 cells and holds broad-spectrum antiviral properties. Its efficacy notably surpasses that of the reversible inhibitor 3-deazaneplanocin, especially in combating vesicular stomatitis, evidencing a higher potency with ID50 values of 0.07 μg/ml for Neplanocin A versus 0.3 μg/ml for 3-deazaneplanocin.Fórmula:C11H13N5O3Cor e Forma:SolidPeso molecular:263.3Myxopyronin A
