Alkynes in medicine

Often used Alkynes in medicine 

There are not many known Alkynes that hold a good outcome for pharmaceuticals. They are rather toxic and dangerous for humans. Stay alert and be careful when working with Alkynes in the lab or on a workspace.

Although specific Alkynes known as ene-diynes possess a very strong and aggressive anti-tumor compound. These molecules are cyclic and contain an alkene (double bond) in between two alkyne (triple bonds) functions, therefore the name "ene < alkene" and "diyne < two alkynes".

An example of this anti-tumor working agent is the drug calicheamicin. When released into the tumor cells, it undergoes a strong reaction when it gets in contact with DNA, known as the Bergman cyclization. It will cleave the DNA and thus destroying it. 

Structure of calicheamicin: 



Trivia: it is rumored Alexander the Great was poisoned with calicheamicin. His death has had the same symptoms as of someone that would drink from the water of the river Styx (river of death and hell), which would've been contaminted with calicheamicin.

Coca-Cola: Life - myth or truth?

"Coca-Cola Life" Recently the Coca-Cola company released a new beverage: the Coca-Cola Life drink. It should contain less sugar than the normal Coca-Cola drink; a part of the sugar is replaced with the recently approved sweetener from the Stevia plant (stevioglycosides). It's being sold as a 'natural' drink, but those stevioglycosides are as natural as the chemical sweetener aspartame found in Light and Zero drinks. However it is true that the amount of sugar is much lower (being reported as 33%, some say it's around 20%); yet approximately still 3-4 sugar cubes / 33 cl can (5-6 in a normal can). I bought it myself and found that the flavor has not really changed from the original Coca-Cola, however it does taste more "flat" - but definitely true it yourself. The outside of the can has the colour green. I personally do not associate this "healthy - natural" colour with Coca-Cola, but it's growing on me. In sum...

Erythropoietin: definition, structure, synthesis in vivo

Definition: EPO: = erythropoietin   A glycoprotein hormon-like structure, a sialoglycoprotein, which is an important factor in the survival, growth and proliferation of erythroid precursor cells (EPC) and it improves the de novo creation, differentation and growth of red blood cells (RBC). Thus, EPO controls the erythropoiesis = production of RBC. EPC: these are cells that are located in the bone marrow, will eventually form the RBC. RBC: cells responsible for the transport and distribution of oxygen throughout the body. Structure: Built out of 165 aminoacids (AA). They are all connected and form 1 polypeptide chain.  Although, within the chain, there are 2 disulfide bonds.  Respectively on positions: Cys7-161 and Cys29-33  Cys = cystein and the numbers indicate the positions these AA are located. Cystein structure. Available  sulfide  group for bonding There are also 4 positions where there is a possibility for glycosylation  Namel...

Alkynen: Elektrofiele additie

Elektrofiele additie: Waterstofhaliden op alkynen Voorbeeld van waterstofhaliden: HCl, HBr, HF, HI Gebruik van één equivalent waterstofhalide met alkyn (dus 1:1 geen overmaat geen tekort) Bij een overmaat aan het waterstofhalide zal een tweede reactie plaatsvinden op het gehalogeneerde alkyn, ter vorming van een geminaal regioisomeer.
