Who was the discoverer of leprosy?
G.H.A. Hansen, discoverer of M. leprae in 1873 The history of leprosy was traced to its origins by an international team of 22 geneticists using comparative genomics of the worldwide distribution of Mycobacterium leprae.
What is the root word of leprosy?
The word leprosy comes from ancient Greek Λέπρα [léprā], "a disease that makes the skin scaly", in turn, a nominal derivation of the verb Λέπω [lépō], "to peel, scale off". Λέπος (Lepos) in ancient Greek means peel, or scale, so from Λέπος we have Λεπερός (Λεπερός= who has peels—scales) --> and then Λεπρός(=leprous).
How was leprosy treated in the 1960s?
They were given by injection and orally, and were believed to cure some people, but results were often disputed. It was not until the 1940s that the first effective treatment, promin, became available. The search for additional anti-leprosy drugs led to the use of clofazimine and rifampicin in the 1960s and 1970s.
How did leprosy spread to the New World?
They created a map of the dissemination of leprosy in the world. This confirmed the spread of the disease along the migration, colonisation, and slave trade routes taken from East Africa to India, West Africa to the New World, and from Africa into Europe and vice versa.
What is the derivative of dapsone?
Dapsone (4,4′-diaminodiphenylsulfone) is an aniline derivative belonging to the group of synthetic sulfones. In 1937 against the background of sulfonamide era the microbial activity of dapsone has been discovered.
What is dapsone made of?
Dapsone is a synthetic derivative of diamino-sulfone with anti-inflammatory and anti-bacterial properties.
What is the mechanism of action of dapsone?
Dapsone is a chemical class different from sulfonamides but its mechanism of action is similar to sulfonamides via inhibition of bacterial synthesis of dihydrofolic acid by competing with para-aminobenzoate for the active site of dihydropteroate synthase.
What class is clofazimine?

It is also used with other drugs to treat Hansen's disease. Dapsone belongs to a class of drugs known as sulfones. It works by decreasing swelling (inflammation) and stopping the growth of bacteria.
What is anti leprosy drug?
For the treatment of patients with multibacillary leprosy, WHO recommends a combination of rifampicin, clofazimine and dapsone; for patients with paucibacillary leprosy, MDT uses a combination of rifampicin and dapsone.
What is the mechanism of action of sulfonamides?
Mode of Action: The sulfonamides are structural analogues of para-aminobenzoic acid (PABA) and competitively inhibit dihydropterate synthetase, an enzyme that facilitates PABA as a substrate for the synthesis of dihydrofolic acid (folic acid).

How are thiacrowns synthesized?
The main group of macrocyclic sulfur compounds, the thiacrown ethers or, in short, ‘thiacrowns’, are mostly synthesized by reacting α,ω-dithiols with α,ω-dihalides under alkaline conditions. Although there are other synthetic routes, that is, via thioacetamide or catalytic ring-opening cyclooligomerization (ROC), the yields provided by these syntheses are significantly lower than that of the general procedure. Macrocycles substituted at a carbon atom are formed by reacting the appropriate substituted educt or by applying butyllithium to macrocycles bearing a thioacetal moiety. In the latter case, a hydrogen is abstracted and other substituents can then be introduced to the molecule. The main reactivity of the thiacrowns is dominated by the soft nucleophilic character provided by the sulfur atoms. This makes these thiacrowns especially suitable to chelate transition metal cations and numerous homoleptic and heteroleptic complexes are known and mostly characterized. These chelating properties can be used to design metal-selective electrodes where the appropriate thiacrown is embedded as ionophore affording a route to extracting heavy metals from wastewaters when it is bound to a polymeric backbone. In both cases, selectivity is provided by ring size and number of sulfur atoms within the macrocycle.
What are the effects of sulfur in yeast?
In general, sulfur compounds have negative impacts on the sensory profile of foods, with rotten, smelly, and eggy descriptors given to compounds such as hydrogen sulfide, dimethyl sulfide, mercaptans, and thioesters. Saccharomyces cerevisiae differs by strain in the production of sulfur compounds, but yeasts such as P. membranifaciens, Dekkera spp., and Wickerhamomyces anomalus can also produce significant amounts. Volatile sulfur production by Y. lipolytica is considered important for distinctive aroma production during the maturation of cheeses; however, this is not considered to be a spoilage process.
Is sulfur a precursor to hydrogen sulfide?
Many sulfur compounds, including inhaled hydrogen sulfide, are toxic. Only a few of the numerous sulfur compounds in nature serve as significant precursors for human sulfur homeostasis. Among these the amino compounds methionine, cysteine, homocysteine, and taurine are most notable, because they contribute to the synthesis of the sulfate donor 3′-phosphoadenosine 5′-phosphosulfate (PAPS) on top of their function as precursors for proteins and other specific compounds.
Is garlic a sulfur compound?
Garlic contains at least 33 sulfur compounds, several enzymes, 17 amino acids, and minerals such as selenium. It contains a higher concentration of sulfur compounds than any other Allium species. The sulfur compounds are responsible both for garlic’s pungent odor and many of its medicinal effects. Dried, powdered garlic contains approximately 1% alliin (S-allyl cysteine sulfoxide). One of the most biologically active compounds, allicin (diallyl thiosulfinate or diallyl disulfide), does not exist in garlic until it is crushed or cut; injury to the garlic bulb activates the enzyme allinase, which metabolizes alliin to allicin ( Figure 46.1 ). Allicin is further metabolized to vinyldithiines. This breakdown occurs within hours at room temperature and within minutes during cooking. Allicin, which was first chemically isolated in the 1940s, has antimicrobial effects against many viruses, bacteria, fungi and parasites. Garlic oil, aged garlic and steam-distilled garlic do not contain significant amounts of aliin or allicin, but instead contain various products of allicin transformation; none appears to have as much physiologic activity as fresh garlic or garlic powder ( Figure 46.2 ). 4

Patients with localized leprosy would be treated for only six months, and the most advanced cases would receive treatment for only two years. Initially, these methods were highly controversial, but, as they were shown to be successful, they became the standard of treatment.
What was the miracle of Carville?
In 1941 doctors at Carville began to test a derivative of the compound, called promin, on patients. Promin had drawbacks—it had to be given intravenously, on a regular schedule, and for a long period of time—but it reversed the course of the disease in enough cases to be heralded as the “miracle at Carville.”.
Where did Hansen discover leprosy?
It was in Norway that Hansen identified the leprosy bacillus in 1873. (At that time leprosy affected about 2.5 percent of the population of Bergen, where Hansen did his work.) This great discovery made possible the modern era of treating the disease itself, rather than merely containing it or treating the symptoms.
